Adapter that will allow a USB keyboard to plug into a tablet???
One big reason I wouldn't want a tablet is that aiui they have no jack
into which a full sized keyboard can be plugged. But they do have jacks. Is there an adapter that will allow a USB keyboard to plug into a tablet. Or perhaps a PS2 Keyboard. :-) A lot of these things seem to take a couple years. Do you think someone will make one soon or eventually? Thanks. |

What happened when you plugged in a USB keyboard into the USB port (which you say this undentified product has)? The [micro] USB port might just be for charging, not for USB devices. Maybe they expect you to use Bluetooth to connect external devices, if the product has the Bluetooth feature. Don't know because "tablet" doesn't identify brand and model. Here's just one example: http://dlcdnet.asus.com/pub/ASUS/Eee..._Guidebook.pdf page 24 Tells how to use a USB-attached keyboard. But that is for THAT brand and model. You didn't identify yours. If you're asking about tablets in general then the answer is "Yes, some tablets let you use a USB keyboard and, No, some tablets do not." |

Do you think someone will make one soon or eventually? Thanks. There were only 25 million hits on Google. I suggest trying again in a year or two. Knowing nothing about tablets, I'll give it a try... 1) The simplest adapter would be microUSB to regular sized USB. The problem with that, is the regular USB is *male*, and is intended to plug the tablet into a desktop computer (for charging or for sync). 2) The other kind of device I could find, is female on the regular-sized USB end, but to use it, the Tablet documentation has to mention OTG or "On-The-Go" USB ports. http://www.startech.com/Cables/USB-2...Female~UUSBOTG The low price suggests that thing is passive, and there is no chip inside. It's just a way to get a cable with a female on the end. The magic is inside the tablet. An OTG port handles the details. Regular USB goes from host to peripheral. It was not intended to go from host to host (at first). The OTG option (if designed in), adds more options for gender reassignment (OTG device can be a host or can be a peripheral). http://en.wikipedia.org/wiki/USB_On-The-Go You'd think there would be a picture in the manual, but the cheapest mobile devices you can buy now, they come with a single sheet of paper in the box. Which doesn't offer much possibility of providing useful instructions. Paul |

How dare you want to use a keyboard for faster input than what a finger or mouse can provide. How precocious to perceive 1-finger pecking around an online keyboard as slow input. Please don't whip me, Sire. I can't help myself. The manual for the *unidentified* secret tablet doesn't tell you what the ports are used for? What happened when you plugged in a USB keyboard into the USB port (which you say this undentified product has)? No, Sire. I never said it had such a port. All I know about tablets is what little my ex-girlfriend tells me, and she's had hers for 6 months without ever showing it to me. Is it all right, Sire, that I have an ex-girlfriend? I will abandon her if you say so. The [micro] USB port might just be for charging, not for USB devices. Maybe they expect you to use Bluetooth to connect external devices, if the product has the Bluetooth feature. Don't know because "tablet" doesn't identify brand and model. Here's just one example: http://dlcdnet.asus.com/pub/ASUS/Eee..._Guidebook.pdf page 24 Sorry. It took me a while to do this. Hey, it uses mice and keyboards too. And the tablet has a USB port. And it says to connect more than one thing, use a powered hub. I have one of those!! Tells how to use a USB-attached keyboard. But that is for THAT brand and model. You didn't identify yours. I have no brand or model. Another friend asked what I would recommend, and I told him tablets were becoming popular and were light, but afaik they wouldn't use full-sized keyboards, but then I started to wonder why they didn't. Then later yesterday he wrote that his son probably wanted a laptop, not a tablet. In his first email he only said "computer". If you're asking about tablets in general then the answer is "Yes, some tablets let you use a USB keyboard and, No, some tablets do not." That may or may not interest him, but it sure interests me. |

Those devices draw power and the batteries for tablets aren't very big. A powered hub lets you plug in multiple devices but has the powered from an external source (i.e., wall outlet). Just remember that all devices plugged into the same hub or port have to share that USB controller. If you hookup a printer (if that's even supported) then a print job's traffic could make jerky the mouse or keyboard attached to the same USB port. If you use a wireless mouse and keyboard that are paired (use the same transceiver plugged into the USB port) then you could probably get away from having to use a powered USB hub. There would be just the one USB transceiver used by both the wireless mouse and wireless keyboard. That transceiver will still suck up some power and drain the tablet's battery. If the tablet uses a separate charging port, like for a wall adapter, then you could leave the tablet plugged into power and not be concerned about the power draw of the wireless USB transceiver. Another friend asked what I would recommend, and I told him tablets were becoming popular and were light, but afaik they wouldn't use full-sized keyboards, but then I started to wonder why they didn't. Some will dock with a keyboard. The ones that I've seen like this have larger screens. When plugged together, they look like a toy computer: screen (tablet) and keyboard. You can undock the tablet and wander around with it sans the keyboard. With laptops, you can connect a full-sized keyboard, a regular mouse (not those small portable/laptop models), and either have them wired or wireless. They also have a VGA port so you can connect them to a full- sized monitor. You can turn a laptop into a weak desktop but that may all you need for a laptop-as-desktop setup. Some laptops even have docking stations so all you have to do is push the laptop into the docking station to start using the full setup. If the laptop doesn't move around much, like only during vacations, then the cost of a docking station isn't needed and you can just leave the wired stuff and wireless transceivers plugged into the laptop while is it stationary. When my desktop died and before I replaced it, I used my laptop this way with a full monitor, keyboard, mouse, printer, and powered speakers for several months. It was usable for most everything except video games. As for tablets, I don't recall seeing one with a VGA port so you can't quite frakenjob it into a limp desktop. As big as is the tablet's screen is as big a screen as you'll get. You can get laptops that are pretty small and besides the USB ports for connecting keyboard and mouse they also have a VGA port to use with a full monitor. However, considering the cost, trying to setup a frakenjob of making a laptop into a desktop would only make sense if you really have a need to have it portable at times. |

Would that work? Don't know. Could be the load of the keyboard and mouse (or a wireless transceiver) could lower the voltage to the tablet. While less voltage means the tablet's battery would charge slower, it could also mean more current has to be delivered. I wouldn't mix the charging function with the device function unless the manual indicated they could be mixed. They do mention using a powered hub so the USB port to the tablet would also be powered. Make sure you get a powered USB hub that can deliver FULL power to each port. If, say, it had 4 ports but only a 1A power adapter then that 1A gets shared across the ports. For a 4-port powered hub, you'd want a 2A power adapter to make sure each port could get its .5A rated load. I don't know that the tablet would know it was getting the 5V power from the USB port on another computer or from a USB port on a powered hub. Either probably works. **My cellphone only has one USB port too, for charging, but there is no way to use an external keyboard with the cell phone. I wish there were. Some cell phones even have the data function disabled. All you can use the miniUSB port for is to charge. You can't use it to transfer files to a computer. That way they get their customers to use up minutes by sending the pics on the cell phone via e-mail. |

However, considering the cost, trying to setup a frakenjob of making a laptop into a desktop would only make sense if you really have a need to have it portable at times. Charging and the OTG protocol is addressed in the Wikipedia article. A lot of these OTG hubs, there is no external power input to the hub. If external power was applied to the hub, chances are it would be prevented from flowing backwards into the OTG port. (At least, as long as charging is not supported.) https://brando.com/prod_img/zoom/SUBAD004500_01_L.jpg In the case of the Nexus 7, there's some hacker activity out there, to do both. http://mehrvarz.github.io/usb-host-m...gement-nexus7/ https://sites.google.com/site/sonicb..._OTG_CABLE.png From a hardware perspective, you'd hope, eventually, a USB hub product would have the appropriate logic (presentation of the right sense resistor value), to solve the hardware end without using that Y cable. But the other part, is the behavior of the Nexus when presented with varying power information. It's basically some level of conflict between OTG sensing and battery charging. The software plays a part too, as otherwise, an attempt to charge might be ignored. There's probably a thousand pages of USB standards information now, and not something you'd wade through for fun. Constant retrofitting to the specs, means the standard never sits still, and the chip designed yesterday always needs some slight tweak to satisfy requirements it was never intended for. (OTG as complicated extension for things missing from tablet SOC). They could easily put a few more microUSB ocnnectors on a tablet, to allow more flexibility in these things. Or, for example, a barrel connector would allow powering without a lot of side-effects. But they'd never consider doing such a thing, because it's too simple. Instead, all the functions will be rammed through one tiny five pin plug. A thousand pages of USB standards, and kernel software support. And then the end user will be left wondering, why his tablet didn't charge last night, like it was supposed to. Paul |

If you have an Android tablet it should be easy. That is what I do with my Android "PC on a stick". |
