I'm currently trying 2 x belkin 3 port cards off the shelf from PC world (UK)... (due to speed of availability...) 2 ext 1 int. They are Mac compatible and so far no problems....

Also have tried 2 of the 'SUNIX 1074NC with NEC D720101AGM chipset (4+1 port cards) from span.co.uk - cheapest available for Macs. again - no problem in other macs...

The 4 macs that did display this dongle issue have 3 different types of USB card in them - 2 have 'UH2-255', 1 has new 'SUNIX 1074NC' 1 has old 'Orange USB'....

SO this doent really point to any particular brand of card being an issue, as all Macs had the same problem at the same time after a 'warm-restart'

I would still favour Richards explanation of a driver model change in the OS - failing any other reason - it is unlikely to be my 'disk image build' as there are a number of other identical servers with no issues.....

I will be testing 10.4.7 next week - will let you know if the production had any further issues, or if it was just a one-off.

Cheers
