Topic: USB problems
I got a Chumby classic at Best Buy for $19 on the as is cart !
Seams to work with my terminal program and an FTDI USB cable connected to the TX/RX/GND pins inside.
I can put .img files on a 1 to 4gb SD card ok with Win7 and the Win32DiskImager program.
So far so good !!
I can't seam to get the wireless or the other usb port to work.
I tried 6 different usb drives formatted in FAT32 clean with just the tgz files or the update1 update2 folders on them at root but the update selection wifi or usb doesn't light up, just grayed out.
That is why I used the .img files (2 different ones) and windows to update an SD card.
They are rom-falconwing.img and rom-chumby-falconwing-chumby-starter-image.img
Both .img files work fine.
The Wi-Fi usb dongle works fine on my windows computer ! It is the RT73 from the Chumby. So we rule out a bad wifi card.
I tried a usb keyboard (2 different ones) and they don't seam to work.
I measured the voltage at the 2 usb ports and both are 5.17 vdc. I have not looked at the data lines with a scope yet.
On boot up I don't think I see a driver for the RT73 load up.
I think I do see the usbhub drivers load ok.
I don't see a ttyusb in the /dev dir.
I do have a usbdev1.1_ep00 and a usbdev1.1_ep81 in the /dev dir.
When I do a iwconfig I get lo no wireless extensions
when I do a iwlist wlan0 scan I get wlan0 Interface doesn't support scanning.
Same with the usbdev1.1_ep00 or 81
So, the usb interfaces don't seem to exist.
Any other things I can try ?
