Hi ,
I am replying to this as I had originally posted the issue in the link
provided by Pablo.
The issue with mine was that it was plugged into a laptop usb port which
was on an internal usb hub and hence couldn't handle duplex. I applied the
patch on the 3.0.13 kernel and it worked beautifully, but is now causing
other problems (my internal laptop web cam that is also plugged in via
another internal usb hub does not work. It works with the kernel without
the patch). I will be testing this more in detail and filing bug reports
if required.
My device is a usb 1.1 device and it had problems in duplex mode. I have
another usb 1.1. card which worked just fine. Alexander mentions that his
device works just fine in usb 1.1 mode and has problems in usb 2 mode, so I
don't think that it is not the same thing as my issue.
Alexander, just curious, are you plugging your card into a hub or directly
into your PCs usb ports?

All the data continuously generated in your IT infrastructure
contains a definitive record of customers, application performance,
security threats, fraudulent activity, and more. Splunk takes this
data and makes sense of it. IT sense. And common sense.
