This is probably a repost on the CF, but I would like to know if anyoen with 4700 used this? |
I've got a 4700 and that exact card. Honestly, I've never once used it. I got the USB Host card exclusively for using with a USB keyboard, but I never had any luck with it. It is recognizing that I plug in USB devices, but it always comes up with the prompt "Unidentified USB device" and asks for a device driver when I plug in the USB devices that I own.
If you want to know anything about it, lemme know, I'll see what I can do. |
Most people are able to use their USB keybard with USB-enabled PDA's / Ratoc CF USB host cards without additional drivers. (See, e.g.,
http://www.firstloox.org/forums/showthread.php?t=2356 ) I think the problem is related to your keyboard's current requirement: if its current is (way) above 100 mA, then it won't be recognized by the USB driver. Some USB keyboards require even 250 mA current. I know it (a keyboard with 250 mA current at 5V) sounds unbelievable - I haven't measured it myself so I can't really say for sure that IT is the problem.
Unfortunately, your CF card doesn't allow for external power supply, unlike the Twin Paradox / Cypress Semiconductor card (

BTW, you could also test the trial version of the Deje driver (
