USB card manufacturer is unknown..... just have markings of 'UH2-255', one of the servers has a newer card - 'SUNIX 1074NC' 2 of the Macs are recent 2.7G liquid cooled. The other 2 macs both 2.0G one about 6 months old - the other about 2yrs.

The way the cases are cabled, the CIB always tends to be in the Mac port, not a PCI card port.... so havent experienced that issue. Dongles are always installed internally on the PCI card, Havent had any issues reported when on an external mac port.

Was running a different V4 mac this weekend (same software re-build) - and had no issues the whole weekend....

Will see if there have been any further issues on particular production,

Cheers
