Hi there,
I'm pretty desperate now. I tried to get USB to work. I used:
Board: MSI K7T266266A (6usb 1b,no raid)
System: SuSE8.1 kernel 2.4.19-4GB
and a USB modem that i can't get to work
linux:/home/oli # lsusb
Bus 002 Device 003: ID 0483:7554 SGS Thomson Microelectronics 56k
SoftModem
linux:/home/oli # minicom
minicom: cannot open /dev/ttyACM0: Invalid argument
and a HP usbprinter which will do nothing if i do a
linux:/home/oli # echo "wont work" >/dev/usb/lp0
linux:/home/oli #
I had a look at www.linux-usb.org and read the "usb-guide" and
"usb programming guide". But i could not find any FAQ with google.
The printer will work just fine on Win98 using the Drivers
supplied on the Vendor-Disk (HP).
Is there any debug facility to track what is going on in the
usb-subsystem?
Help would be appreciated!!!
TIA, Oliver
I have included the output of lspci, lsmod, lsusb and dmesg.
