for the better part of this day I have been trying to get my HASP dongles recognized by Desktop for Mac. Right after installing Desktop for Mac beta 6 they worked without a major issue but since upgrading to RC1/RC2 all I seem to get is the "cannot connect, wait 5-10 seconds" dialog. I've tried to downgrade to beta 6 but this helped once. After a disconnect/connect Desktop did not want to connect to my HASP dongles.
From the messages on the forum I see a lot of issues reported related to USB support. For me, being able to use my hasp dongles and measuring devices is essential. At the moment support for these devices is very unreliable.
My hope was RC2 would fix these issues so I could go and order the full upgrade license for Desktop. Today when I start Desktop I get a message stating I need to upgrade within 5 days. That was the moment I took the step to install Boot Camp. Not very friendly to use but at least my USB devices WORK!
Until I will be able to connect to more then two USB devices from Desktop I will not upgrade and I will advice my collegues to also hold back from upgrading. I'm going to wait until this years WWDC to see what Leopard has to offer.

ps. I have never had any issue whatsoever with my USB devices on my Dell running VMWare.
