I was intending on testing this on the Davinci EVM board tonight, but for some reason although the USB controller is recognized by 2.6.31-rc7, it's not seeing any devices when they are plugged in. I get no announcements from the kernel, etc. 2.6.18 works fine on this board, and 2.6.31-rc7 is seeing devices I plug into the USB controller on my board that's having this TX FIFO issue. -rc5 also is not recognizing devices. Correct me if I'm wrong, but regardless of hotplug daemons running (and it is), it should still show up in /proc/bus/usb/devices, should it not?
I'm a little puzzled as to why basic USB functionality isn't working. The kernel build options are identical except Ethernet and NFS being enabled on the EVM build. dmesg output grepped for 'musb' is the same, as is the output of /proc/bus/usb/devices. #cat /proc/bus/usb/devices T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 1 B: Alloc= 0/800 us ( 0%), #Int= 0, #Iso= 0 D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=1d6b ProdID=0002 Rev= 2.06 S: Manufacturer=Linux 2.6.31-rc5-davinci1-06206-g34b63d9-dirty musb-hcd S: Product=MUSB HDRC host driver S: SerialNumber=musb_hdrc C:* #Ifs= 1 Cfg#= 1 Atr=e0 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.)
