Been tinkering with the E1 here, and I've run into my first issue. For whatever reason, the FWUpdateEndUser.exe program refuses to start, and I can't update the firmware. Killing the process in Task Manager does -nothing-, mandating a reboot to give myself another shot at things. Following the PDF guide to install their C-Media drivers over the USB Composite device did absolutely nothing either, and compatibility mode is rubbish as well!
Running up-to-date W7 x64. Checking event viewer now, but any ideas in the interim? I recall reading about a USB selector mode that tells the E1 to operate at USB 1.1 or USB 2.0 for audio, but I can't find it again for the life of me, and I'm wondering if that may help matters.
FWIW, I did get the MCU upgraded. Now I just need the Firmware done.
