Did you people having this issue contact Brittany yet? Shes trying to keep track of things and it would be good for you to contact her as maybe she can get this somewhere and get fixed.
Now while unofficial, I am hearing this issue wasn't caused by DISH's software team, but was caused by a chipset driver update that seemes to have hosed some older USB devices. If this is indeed the case I can see why DISH didn't know and why they are slow in fixing it as they need the chipset company to fix its drivers and release them to DISH so they can be pushed out to all.
DISH does not hate you guys nor do they want you to buy new USB dongles. I am rather sure they didn't even know this was an issue until they saw it posted.
Again contact Brittany if you are having this issue, so she has your info and hopefully she can do something for you to keep you happy.
