Hello,
I have a problem with opening non-control bulk endpoint of Echelon USB
Network Interface which was detected as ugen0.
There is no problem with opening control endpoint with open(2) like following:
open("/dev/ugen0.00",O_RDWR,0)
After that the control endpoint (endpoint 0) accepts every ioctl(2)
calls listed in ugen(2) manual ( USB_SET_CONFIG, USB_GET_CONFIG_DESC
etc..)
However when I try to open any endpoint from 1 to 15 open(2) fails and
error "Device not configured" is returned.
This device does working well under Windows, and I saw *.inf driver
file - Windows recognize this device as FTDI. OS 4.5 recognize this
device only as ugen0.
Below I also add output from some ioctl(2) calls which I made for
information about the device, maybe it could be helpful.
Thanks in advance,
Milosz Jakubowski
