Hello, I'm trying to troubleshoot a problem with a custom USB device based on the Atmel AT43USB326 chip. The device is a simple keypad and integrated audio device for use by the visually impaired. On Windows XP the keypad and audio devices are recognized and I can use Wordpad (ugh) to see that the key events from the keypad are received. On both a Linux From Scratch (kernel 2.6.16.18) and Fedora Core 6 (2.6.19-1.2895.fc6) install, however the keypad and audio devices aren't recognized and I get the following dmesg output:
usb 1-1: new full speed USB device using uhci_hcd and address 2 usb 1-1: configuration #1 chosen from 1 choice hub 1-1:1.0: USB hub found hub 1-1:1.0: config failed, hub has too many ports! (err -19) I've recompiled my LFS 2.6.16.18 kernel for usb verbose debug and usbmon support. Attached please find the dmesg, /proc/bus/usb/devices, and usbmon output when plugging in the device. Any help would be most appreciated. ============= /proc/bus/usb/devices ============ T: Bus=03 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2 B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0 D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=0000 ProdID=0000 Rev= 2.06 S: Manufacturer=Linux 2.6.16.18 uhci_hcd S: Product=UHCI Host Controller S: SerialNumber=0000:00:10.2 C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr= 0mA I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub E: Ad=81(I) Atr=03(Int.)
