Please forgive if this has been previously addressed, but I could not find the topic in a Forum search.
I recently purchased a set of USB 2.0 loopback devices and I am trying to get rough estimates of USB bulk transfer speeds in Win7 and Ubuntu 10.04, using the identical underlying host PC hardware (Intel ICH9 host controller, pentium dual-core 2.93 Ghz, 2G Ram).
In win7-32bit, I see average benchmark transfer speeds of 295 Mbit/s which seems normal. In Linux (2.6.32 kernel), I see the same hardware producing only 6 Mbit/s using the BurnInTest v3.1 software. I would like to understand why the results are so different and what I am possibly misconfiguring between these tests.
Thanks,
