Jack,
I am working at Germanys largest ham radio store, and we sell a lot of 
microHam products, whether it be the microKeyer or the USB 1/2 interface. I 
do the support for these products for our customers.

Let me tell you that the product you bought really is capable if what it was 
advertised for. If it doesn't, it can have two reasons: it has a malfunction 
or has been misconfigured. 

Yes, I have seen malfunctioning microHAM USB2 interfaces, but the rate is 
fairly low, I estimate well below one percent. But if somethign fails it's 
mostly the CAT part of the interface.

So my advice would be to check all settings, including the jumpers, again. The 
urouter software has a lot of options and has a somewhat steep learning 
curve. Make sure that you have the latest version of that program 
(downloadable at microham.com).

If you are really sure that all settings are Ok got to your dealer, they 
should offer you a replacement unit.

This is a very helpful diagnostic, and might be an indicator that indeed the 
CAT portion of the interface is not working correctly.

If you have the standard IF-10B interface installed in your TS-940 and if you 
have the right version of the cable (called USB2-TS6 of DB15-TS6 if you 
bought the cable separately) it does work. We have sold several of them to 
TS-940 users.
