G'day,
Where can I find benchtests performed for USB2 compliant controllers on
NetBSD-i386 that would give some indication on the expected maximum data
bandwidth? Currently, I'm only managing a maximum of 4MBytes/sec with a
Intel 82801DB USB EHCI Controller (rev. 0x01) connected to a Cypress 7C63013
device (FX2), which is a long way off from its theoratical 480Mbits/sec of a
fullspeed USB2 interface.
Are there any suitable open source utilities for the purpose of testing and
verification of USB2 interface performance on the NetBSD-i386?
With many thanks in advance,
cheerio Berndt
