Hi all
My problem was not solved with ANY "us-122" drivers in ANY compatibility mode.
But what DID actually work was installing the driver :
US-122mkII & US-144mkII Drivers for Windows 7, Vista, XP driver ver 2.03 (64-bit) - 1.76 MB
at the page :
http://tascam.com/product/us-122mkii/downloads/
This is the driver for the model US-122MKII.
As always: Download, unzip, right click the app file called "Setup" and go to "properties" of file.
Then to second tab, the"compatibility" tab.
I checked the box "run as administrator" and also the box "run this program in compatibility mode for".
There I chose Vista, because the file i downloaded (tascam_us_122_144mk2_win64_203) said it was for vista. (Oh..... I have 64b Windows. If you have 32b download the 32b driver instead)
And luckily it works! My friend who has the 144 model also used the equivalent driver.
The system recognizes the card as "us-122" not as mk2, so my guess is that TASCAM obviously made this driver to work for this card as well, but never bothered to state it on their site.....
Hope it helps others
