One of the specs for USB2 I noticed, was that it has an transmission error rate of less than one pr. month. I would not blame USB for not transferring data correctly.
The built-in USB2 has several USB hosts, so maybe you can reach your goal of separating usb devices with them ?
Did you connect an extra power cable to the Molex socket on the adapter ? The manual says something about that it should, if you connect devices that gets its power from the USB connection.
The latest driver on startech.com has version 3.0.16.0. I guess that this is the on you are using otherwise try it.
Windows asks you if you want to send an error report to Microsoft after an BSOD. Did you try that ? The answer you get back might include information about which driver that crashes.
Sorry if this sounds like a wild goose chase.
Don't consider this chasing geese since it gives me questions to ask techs at Dell, StarTech, etc., ...so thanks!
Not worried about the slower data transfer or error rate of 2.0, just want to take advantage of the separate 3.0 bus if possible.
Not sure there is a way to isolate a USB2.0 connector, etc., to give me the equivalent of a separate bus like the expansion card does OR that I would want to mess with doing so myself if there was.
Saw the note about power to the Molex but DAC is self-powered so should not be an issue.
When Win7 reboots, no message re error report to MS but a box comes up to search for a fix or information on what failed but progress bar completes and no message on culprit is shown...box just closes!?
