Re: PS/2 - USB Adaptor for keyboard
* Celejar [EMAIL PROTECTED] [070302 01:42]: I'm trying to use a simple (cheap) PS/2 keyboard with a laptop which has no PS/2 ports. There are various PS/2 - USB available all over the internet; I bought a cheap one on Ebay. It is a very simple little thing, and I don't think it has any sort of electronics inside, and it doesn't seem to work. The keyboard is not recognized at all, neither in the console nor in X, it doesn't appear in the output of lsusb, and it isn't recognized by MS Windows either. Does anyone know anything about these things? Do they only work with certain types of keyboards? Do I need to configure anything in software? Should I suspect that mine is defective? Correct; there are no electronics in the PS2-USB adapter. A few years back, a PS2 adapter often was included with a USB mouse. It is likely that all you need to do is use the BIOS setup screen to enable the external keyboard and/or mouse. Once that is done, X and Window$ should see them. Also, any USB keyboard -- including keyboards for the Macintosh -- should work fine with your laptop. I am using a Macintost USB keyboard with my desktop PC; it appears to be of much higher mechanical quality than anything else I saw in the PC department of the computer store.

I did take a quick look into the BIOS and didn't see any such setting; I might have missed something. I'll take another look when I'm back at that machine.

RLH I could try that, but I have a specific PS/2 keyboard that I'd like to get working (it has foreign language characters printed on the keys in addition to the english ones, and similar USB models that I saw are more expensive).

Should I suspect that mine is defective? Correct; there are no electronics in the PS2-USB adapter. A few years back, a PS2 adapter often was included with a USB mouse. Agreed, there are no electronics, however AFAIK USB and PS/2 are different protocols - so they cannot be just swapped by using an adapter. (PS/2 and AT could). There is a trick that USB mice's detects where-im-plugged-into and adjusts protocol/wiring. With PS/2-USB its worse, as PS/2 devices aren't generally made to adjust protocol and switch to USB. I could try that, but I have a specific PS/2 keyboard that I'd like to get working (it has foreign language characters printed on the keys in addition to the english ones, and similar USB models that I saw are Well, i guess you just need to buy the USB keyboard that fits for you.. There are sticky transparent characters available for lot of languages, and they can easilly be sticked to any keyboard (however i agree, characters that are printed on keyboard lasts almost infinitely) Regards, Atis -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Anyway, I'm discussing a laptop, so I want an external keyboard anyway. If I have to, I will buy a USB keyboard, but the ones I saw (with foreign language chars) are much more expensive then the cheap (Asian no-name) PS/2 ones available at Newegg.

Well, usually it's said under with little letters, that you need hardware that supports it. PS/2 have really simple interface - it has CLOCK and DATA pins, however USB is more advanced and don't have CLOCK, just two kinds of DATA, naturally CLOCK isn't in USB spec so no PC motherboard should support anything like that. (see links) Mhm, googling a bit showed that there are actually 2 types of those adapters. One that is just plain re-wiring of PS2 to USB, hoping that device will support USB, another seems to actually have electronics inside, and actually doing conversion of signals. I would say that it should work for you (although no guarantees ;) Links: http://pinouts.ru/Slots/USB_pinout.shtml http://pinouts.ru/Inputs/PS2Mouse_pinout.shtml http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=776087CatId=469 http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1219599CatId=469 Regards, Atis -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
