I hope their "improved USB support" will allow USB audio devices to work with VPC. The stock "emulated" soundblaster in VPC really hurts audio latency & stability in music software (ie Fruityloops), although after installing the DirectX 9 latency was improved becuase of the updated DirectSound drivers.
But still, an emulated Soundcard is never gonna compare to "real" hardware support, and I think if USB Audio works with VPC7, well, thats just as important as a direct harware support for GPU.
Just FYI, my USB Audio device (Ego-Sys U24A) was recognized with the ASIO drivers I installed in Win98 on VPC6. It however produced some horrible distortion when playing audio though it though, I figure it's the lack of bandwidth on the emulated USB ports in VPC. So, it's really close to being possible, hopefully Microsoft is working on this for VPC7.
I'm pretty much using VPC in order to use Fruityloops, which there is no equivelent of for Mac.
I'm running a highly optimized & tweaked version of Win98 SE on my 500mhz G3 (In Panther). It's quite useable so far, even being able to use a handful of VST plugins with the tracks I write in Fruityloops.....but it glitches here & there and latency is only useable at around 200ms, which is a long time in the audio world.
Anyways.........
