Whilst my
2.6.24.7-rt17 kernel and disabling all hardware and services
unneeded for audio seems to have gotten rid of those nasty xruns, I live
in fear that they will return. My main worry is how I organise my USB
devices.
My laptop (ThinkPad Z61m) has 3 USB ports. I have several devices that
need to be connected to them, meaning that I need to use USB hubs.
Here are some assumptions (or guesses) that I have made, on which I
would appreciate comment:
* It would be best to balance the devices across the 3 ports.
* My soundcard is a Behringer UCA202, capable of sampling at a maximum
of 48kHz @ 16bits x 2 channels. I'm guessing that this will have the
greatest data rate of all attached devices.
- Should it have its own port?
Yes. This will probably use more bandwidth than all the other devices
combined.
- Can USB 2.0 take more than this (like another
device?)
No USB 2.0 audio devices have Linux support AFAIK.
