Problem getting data from a USB device

NTDEV
1

I use the following code to read data from my USB device. It works
apparently any problem on Windows XP and Windows 2003, both 32 and 64
bit. But on Win2k IoCallDriver() consistently fails with code C000000D
(STATUS_INVALID_PARAMETER).
Anyone is able to tell me what’s wrong?
Thanks a lot,

Loris

How big is MAX_PACKET_SIZE?

How big is MAX_PACKET_SIZE?

#define MAX_PACKET_SIZE 8000

What is the Max Packet size of the pdx->bulk_in pipe?

Just as a thought you might want to make your MAX_PACKET_SIZE less than that
number and see if it works.

Windows 2000 is more restrictive on the size of the URBs it is able
to chop up. Remember that your bulk endpoint packet size is much smaller
than that, so the host controller driver has to chop it up.

I don't remember the exact limit on Win2K. You might try 4096 or 2048
to see if you achieve good results.
