I am running windows 7 64bit and cannot find a driver for my Tascam US-122. The Tascam website states that: The final drivers for the US-122 are Windows XP (32/64-bit) or Windows Vista (32-bit) compatible.These drivers are available for download here. If you need drivers for a different operating system, you need to upgrade to one of our currently-manufactured audio interfaces. I've tried installing the "US122_x64_Win_Install_3_30" file off their website in compatability mode (vista) but it won't work properly due to incorrect digital signature. I really need some help working around this problem. Thanks, Azazeal.

Hey All,
The best way to get the US-122 working on Win7 is to;
-Download latest drivers for US-122 from Tascam site
-This will be a Vista 32 or 64 bit, what ever Win7 you run
-Right click the exe file, go to properties, in the compatibility tab, set compatibility mode to run as Vista SP2 version.
-Install
-Then check drivers, firmware updates
-Ensure US-122 not using MS Wavetable GS Synth.
-Set to use Asio drivers
-Check latency settings of US-122, by going to windows control panel and searching for Tascam
-Check latency settings in asio drivers, and untick 'Allow application to take over this device' or whatever it is, this should also disable MS Wavetable GS when US-122 and asio in use in use
-Around the 512 samples should get no clipping/popping, with below 10ms latency for most asio drivers, which is as good as the US gets
-Some asio drivers (Full duplex etc) will give you a false latency figure in Cubase etc, but I have found no clipping/popping or latency with US-122 set to 512 and asio driver set to mid range (around 50ms) on i7 2-3ghz, 8g ram....

Haven't tried it (us-122 + win7 x64) but you could turning off 'forced driver signing'. http://www.tipandtrick.net/2008/permanently-turn-off-and-disable-64-bit-x64-windows-vista-forced-driver-signature-signing-with-readydriver-plus/

Win7 32bit doesn't have this feature, only win7 64.

You should contact to technical support provider .

If you have windows professional you can run US-122 win 32 bit driver. you have to run win 7 pro in xp mode then install the driver. you have to go to the microsoft web_site to download xp mode.
