Hi,
it seems that our problem with the USB-pendrive is easy to explain,
but not difficult to solve:
We are using a ohci controller on a cache-incoherent system (IBM PowerPC 405).
This causes a lot of problems in the USB system during DMA'ing to non-cacheline-aligned
memory regions.

I did that before. Seems to work under 2.4.18 (SuSE kernel).

No, I cannot try that, since this kernel is not supported by our custom board.
Can you enable OHCI_VERBOS

Hi,
I have a problem with the usb-storage driver on a PowerPC hardware.
My Linux Kernel is 2.4.21-rc7 from the PowerPC devel tree.
This is what happens:
First I load the usb-ohci driver (PCI hostcontroller is a Philips ISP1561BM).
This OHCI host controllers has two USB1.1 hosts, one USB2.0 host.
