Hi, I'm using an embedded system (IXP42x) with an ISP1563 HC, with kernel 2.6.29-rc6. When only the OHCI driver is loaded, the storage driver does not recognise an attached high-speed or full-speed MSC device. The problem seems to be some sort of hang after a short read. What could cause this ? Thanks, Zoltan Log with verbose debug: [ 1889.220000] usb-storage: Command MODE_SENSE (6 bytes) [ 1889.230000] usb-storage: 1a 00 3f 00 c0 00 [ 1889.230000] usb-storage: Bulk Command S 0x43425355 T 0x4 L 192 F 128 Trg 0 LUN 0 CL 6 [ 1889.240000] usb-storage: usb_stor_bulk_transfer_buf: xfer 31 bytes [ 1889.250000] drivers/usb/host/ohci-dbg.c: SUB c1e07200 dev=2 ep=1out-bulk flags=c len=0/31 stat=-115 [ 1889.250000] drivers/usb/host/ohci-dbg.c: data(0/31): 55 53 42 43 00 00 00 04 c0 00 00 00 80 00 06 1a... stat:-115 [ 1889.270000] drivers/usb/host/ohci-dbg.c: RET c1e07200 dev=2 ep=1out-bulk flags=c len=31/31 stat=0 [ 1889.280000] usb-storage: Status code 0; transferred 31/31 [ 1889.280000] usb-storage: -- transfer complete [ 1889.290000] usb-storage: Bulk command transfer result=0 [ 1889.290000] usb-storage: usb_stor_bulk_transfer_sglist: xfer 192 bytes, 1 entries [ 1889.300000] drivers/usb/host/ohci-dbg.c: SUB c1de1d00 dev=2 ep=1in-bulk flags=205 len=0/192 stat=-115 [ 1889.310000] ohci_hcd 0000:00:01.1: urb c1de1d00 path 2 ep1in 91120000 cc 9 --> status -121 [ 1889.310000] ohci_hcd 0000:00:01.1: urb c1de1d00 td ffc050c0 (1) cc 9, len=12/192 [ 1889.310000] drivers/usb/host/ohci-dbg.c: RET c1de1d00 dev=2 ep=1in-bulk flags=205 len=12/192 stat=-121 [ 1889.310000] drivers/usb/host/ohci-dbg.c: data(12/192): 0b 00 00 08 00 03 e3 11 00 00 08 00 stat:-121 [ 1889.350000] usb-storage: Status code -121; transferred 12/192 [ 1889.350000] usb-storage: -- short read transfer [ 1889.360000] usb-storage: Bulk data transfer result 0x1 [ 1889.360000] usb-storage: Attempting to get CSW...
