[arm-allstar] CM108 USB sound FOB

[Doug Crompton]

Daniel,

   That makes more sense. Interestingly that chip will probably work for audio if setup with the code and then would work in the near future with our code and external I/O for COS/PTT. So don't throw it in the trash. You might be a beta test case.  

If you have the amazon link please forward and also when you can the 'lsusb' data.

Hi Doug,
 
I must have been really obsessed with the term  "CM108" to get the name of the 
other chip that wrong. The chip I mean is named HS100B. It is also produced by 
C-Media but lacks a lot of features. Here is a link to the chip: 
http://www.cmedia.com.tw/products/USB20_FULL_SPEED/HS100B
I can't find the datasheet right now, sorry.
 
Attached to this email you'll find a picture of one of the USB sound FOBs 
supposedly equipped with a CM108 chip. I took it a couple days ago to write a 
negative review at amazon. Not that it matters though.
 
I'm on vacation right now and left the boards at home. I will send you the 
complete "lsusb -v" output as soon as I get home.
 
Finding a USB sound FOB with CM119A seems even harder. I went with Peters 
suggestion and ordered the boards from ebay.
