Description David Zeuthen (not reading bugmail) 2009-12-14 07:08:50 UTC 
I have this device

 Bus 001 Device 008: ID 152d:2329 JMicron Technology Corp. / JMicron USA Technology Corp.

 http://www.eagletechusa.com/External_Enclosure/ET-CS2XMESU2-BK.htm

which is blacklisted in libatasmart:

 http://git.0pointer.de/?p=libatasmart.git;a=blob;f=atasmart.c;h=3ff033418a4d8e27f2828a9c0b474d1db9e545be;hb=54f846c2115e7addf5468a9c10ecf9ba844b946e#l2506

If I comment out the blacklist entry, the device indeed chokes (as in, it disconnects) when libatasmart is trying to read SMART status. However, it works fine with smartmontools
