This sentence would have been easier to understand if you had provided
a comma after the word storage.

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

It is good to get some feedback on how the buffer
manipulation should work. I appreciate you taking the
time.
Did you take care about checking byte-endian issues?
Yep, I didn't take enough care. I thought I had, but I

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

Hi All,
I am having an embedded EHCI USB host controller on which i am using
linux-2.6.14
When i am doing bulk file copys between many devices i am facing the
following problem.
The following scenario is observed on the USB BUS Analyzer.
1. Bulk Out Transaction with (31 Bytes USBC
This sounds like the device is getting out of sync (commonly known as
phase error). The host sent a command, but the device was not prepared
to send data at the proper time, and indicated an error with a STALL.
The proper response to a STALL at this point is to attempt to retrieve
status, which
I forgot to mention -- once a phase error is detected, the USB
specification requires the host to issue a RESET to the device.

It is possible that an earlier error in the device left the bulk-in

Could someone tell me the difference between dCBWDataTransferLength field

Hello everyone,
I'm a newbie in kernel hacking and USB and I hope, you or your mailing list
can help me.
I have to write a driver for a USB device, that is recognized as a mass

driver. In fact, it's an
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.
