Having some issues with AM Prisma using the USB adapter

Cgminer 4.7.1
Rasp Pi running latest wheezy
compiled using: --enable-blockerupter --enable-icarus --without-curses

./cgminer -o stratum+tcp://us1.ghash.io:3333 -u xxxx -p xxxx --bet-clk 23

Cgminer spits out a bunch of errors

[2014-11-06 17:44:02] BET0: Unexpected value 00 received
[2014-11-06 17:44:02] BET0: Sync Error
[2014-11-06 17:44:02] BET0: Unexpected value 58 received
[2014-11-06 17:44:02] BET0: Sync Error
[2014-11-06 17:44:02] BET0: Unexpected value 58 received

it then segfaults after a little bit.

I am not sure if my cgminer command is wrong or the USB dongle is the issue.. I have tried plugging directly into Pi and also a power USB hub with the same results.

I get this also but if I restart CGminer a few times it eventually starts hashing fine. Seems that there is something odd with the driver or the chips put out some odd crap at first after power up.

However I have a question about the -bet-clk=23 thing According to CGminer docs this value is x10 so to get 240 you would want 24, which is the default value of the setting. Am I understanding this wrong? Do we need to run the Prisma at 230 not 240? At --bet-clk=23 my unit will not do stable over 800Ghs
