Salve,

I found out that my USB audio-device Egosys U2A is running
with Kernel 2.4.18 and the USB-audio driver :-)

Question:
The vendor of the device says that two or more of the same
devices are not running with M$ - would it be possible to
run multiple of the same device with Linux?

Or does USB devices have uniqe IDs, so multiple device
would not be accessable on the same bus?

Greetings
rob

Egosys Wavterminal U2A USB I/O Sounddevice 
-------------------------------------------------------
Price: 283,77 Euro
http://esi-pro.com/esi-pro/eng/product/wt_u2a/wtu2a.html

Kernel 2.4.18 USB-Audio driver is supporting this device: 
�- analog in (32.0 kHz 44.1kHz 48 KHz) is working
�- analog out (32.0 kHz 44.1kHz 48 KHz) and digital coaxial out is working � �
�- simultaneous EgoSyS U2A: /dev/dsp Laptop build in Soundcard: /dev/dsp1

Not working under Linux 

�- switching to digital in
�- leveling in/output on device

Not tested: 

�- Simultaneous optical out (should work)
�- Switching input source under Microsoft-Windows and plug to Linux. U2A � � 
� �device maybe remember last settings.
�- Microsoft-Windows driver does not supported mulitple U2A device, but � � � 
� �maybe Linux?

Techical hint: 

�- EgoSys U2A digital I/0 is not bit-true because every digital I/O is � � � �
� �resampled and so it lose some Bits: 
� �http://www.solorb.com/dat-heads/digests/V6.200/D275#Msg21 
� �(But I do not think this is tragically ;)
�- analog I/O unbalanced

If you have a U2A, too and live in Belgium, Nethelands or Germany NRW please 
contact me to find out if multiple U2A are running under Linux.
