Hi Alan, Thanks for your response. A bit more context... I dont have a choice in kernel release. I have the ISP1761 example driver which apparently works in 2.6.9 and I can't verify this as there isn't a configuration for 2.6.9 for my platform. I have modified very little to get it to 2.6.14

Hi, I'm trying to understand how the USB Mass Storage Device works in 2.6. Specifically 2.6.14. I see a fair amount of churn in this subsystem. My principle concern/question is how does data from a file on the filesystem get transported to a memory stick? I have dumped info at many stages and

What kernel is this from? According to this log, the READ commands are requesting a block address that makes no sense at all -- it almost looks like random garbage. One read does seem to work though... It's possible that the format of the data isn't quite right, so the filesystem layer is getting

Sounds like the device isn't returning proper INQUIRY data. I've seen that before. It's uncommon, but apparently works somehow with Windows. My guess is that the Windows driver assumes random-access unless told otherwise. Can you recompile your kernel with usb-storage verbose debugging turned
