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. I only use the OHCI controller.
After loading the ohci module, I modprobe the usb-storage driver. It detects my AIPTEK 32MB USB pendrive.
Then I mount /dev/sda1 under /mnt, but this mount never returns. I cannot interrupt the mount call, but the system keeps on running.
Furtheron I noticed that the AIPTEK parts can be mounted when the usb-storage debug option is turned on in the kernel. I that this changed the timing behavior a lot.
Any idea?
I hove no such problems with a USB-CompactFlash card reader attached to this hardware.
My hardware plattform is a custom specific PowerPC design with an IBM405GPr PowerPC CPU.
Here ist my syslog. I do not have hotplugging stuff running, that's why /sbin/hotplug does not succeed.
