Hello,
trying usbtty with my new pxa27x UDC driver I got:
May 11 11:14:26 vvonth kernel: [244681.451000] usb 1-1: unable to read config index 0 descriptor/start
May 11 11:14:26 vvonth kernel: [244681.451000] usb 1-1: chopping to 0 config(s)
May 11 11:14:37 vvonth kernel: [244691.818000] usb 1-1: no configuration chosen from 0 choices
giometti at vvonth:~$ lsusb
Bus 001 Device 016: ID 0525:a4a6 Netchip Technology, Inc. Linux-USB Serial Gadget
Bus 001 Device 001: ID 0000:0000
That looks strange since the device is reconigned but it seems that it
has no configurations at all!
I chacked that when USB host ask:
debug: udc_dump_buffer(), 65: ep0 setup read - buf a1fc0710, len 8
80 06 00 01 00 00 12 00
usbttys answers:
debug: udc_dump_buffer(), 65: ep0 setup write - buf a1fc0734, len 18
12 01 10 01 ff 00 00 10 25 05 a6 a4 00 00 01 02
03 01
saying it has 1 configuration... but the system ignores it!
Suggestions?
Rodolfo
