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@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?
