In my case I tried every USB port on my Windows 7 Home Premium 64-bit desktop, but no luck with the 950. As I said the 350 works fine. CS said all the readers use the same driver, but something isn't correct.
I do not necessarily think this is a Windows 7 Home Premium 64-bit issue. If you add up all the various Windows 7 versions (their are several for 32-bit and 64-bit computers) and realize that their are thousands of different computer models running them, you come up with millions of different combinations. No two Windows 7 systems are identical. Unlike Apple which lacks the knowledge or the guts to create a workable OS that will run on thousands of different computer models by various manufacturers, Microsoft has created a pretty good OS that CAN and DOES operate on such a diversity of computers. The problem is it is often difficult with all that diversity to find the specific issue causing the problem.
In my case I just decided to use my netbook rather than my desktop since the netbook connects to the 950.
As far others: A general set of rules with USB connection problems is:
- Try another USB port
- Back USB ports are often more stable than front ports
- Restart the computer to clear out conflicts
- Don't connect through a USB hub or extender
