Date: Tue, 26 Nov 2002 16:14:58 +0530 [thread overview]
Message-ID: <6DF87017DA95D611AC6000606730DE9B0EC10F@BLREXSR> (raw)
Hi,
I have a custom PowerPC board (IBM 405 Based) with USB - OHCI (Ver
1.1)compliant controller on OPB bus. I have taken SA1111 usb driver as a
refernce and enabled USB. The root hub got initialised and
cat /proc/bus/usb/devices outputs
" T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=
" B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0
" D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxP
" P: Vendor=0000 ProdID=0000 Rev= 0.00
" S: Product=USB OHCI Root Hub
" S: SerialNumber=ef601200
" C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr= 0mA
" I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00
" E: Ad=81(I) Atr=03(Int.) MxPS= 2 Ivl=255ms
But, I get following error message when I connect a USB Mouse
usb_control/bulk_msg : timeout
USB device not accepting the new address.
Also, cat /proc/interrupts gets contnious interrupts for usb-ohci....
Could anybody please tell me as to how to write a USB-OHCI host controller
driver for a non-pci paltform....
regards,
Nageswari
