[Linux-usb-users] Problems with bulk read.

[Daniel Dencker]

Hi.

I have some problems when trying to use the usb_bulk_read function. -1 is returned. The problem is probably on the target side,
but to be sure I wonder if you could please confirm that I am using the function in the right way.

*dev = the handle returned by usb_open
ep = The endpoint address, e.g. 0x82
*bytes = The the returned data.
size = The number of bytes I would like the function to return.
timeout = E.g. 100

If this is correct, do you have any other suggestions how to find the problem. On the target side we are using a PDIUSBD12 and
a H8S2633F.

Control transfers are running, but when calling usb_bulk_read no information is received by the H8.

I understand that this information is far from complete, but if you have any id�as please help.

Thanks!

DD
