m82xxhci USB driver problems
Hi list, I'm trying to get the m82xxhci USB host controller driver working on my MPC8272ADS board, and linux-2.4.25. I can compile and modprobe the module. When I insert a USB pen drive I get the following message: # hub.c: new USB device m8xxhci-1, assigned address 4 Manufacturer: Product: USB Disk Pro SerialNumber: 07531E630012 scsi0 : SCSI emulation for USB Mass Storage devices Which looks okay. But after a long delay I get: # usb_control/bulk_msg: timeout Then after another delay: # usb-storage: host_reset() requested but not implemented # Then after another delay: # scsi: device set offline - command error recover failed: host 0 channel 0 id 0 lun 0 After this final message, but not before, the pen drive device appears in /proc/bus/usb/devices: # cat /proc/bus/usb/devices T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 1 B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0 D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor= ProdID= Rev= 0.00 S: Product=USB MPC8xx Root Hub S: SerialNumber=f0011b60 C:* #Ifs= 1 Cfg#= 1 Atr=40 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.)

MxPS= 2 Ivl=1ms Does anybody have any idea what could be causing this problem? The HCI is clearly able to communicate with the device because it identifies it. But I don't know why the timeout should occur! Alex PS A possibly related problem: I have built sd_mod.o as a module, and I can modprobe sd_mod okay. However, after I have run modprobe I still do not see an sd block device in /proc/devices. I have no idea why though
