Thanks for the delivery, Marto.
The fans are really noisy, I replace them with low CFM and quiet ones,
and run the HEX8A1 with only 175 in frequency and 870 in voltage parameter.
When connected to Linux machine, lsusb will show:
Bus 001 Device 017: ID 04d8:000a Microchip Technology, Inc. CDC RS-232 Emulation Demo
And it appears as a tty device:
crw-rw---- 1 root dialout 166, 1 2g 16 08:51 /dev/ttyACM2
Showed in dmesg:
[ 161.103406] cdc_acm 1-1.1:1.0: This device cannot do calls on its own. It is not a modem.
[ 161.103442] cdc_acm 1-1.1:1.0: ttyACM2: USB ACM device
Running with cgminer:
cgminer version 3.12.3 - Started: [2014-02-15 21:11:05]

While I also run bfgminer with other mining hardware, it seems bfgminer could cause the OS to hang when it probe the tty device.
This can be avoided with run HEX8A1's cgminer first (so the tty device would disappear), or plug the HEX8A1 after bfgminer runs.
Oh, and it runs well with p2pool, with less than 2% DOA, compared to 5~6% DOA for BFL or BitFury devices.
