 I have another datapoint that is interesting. This problem does not appear to 
 be even FreeBSD specific.
 
 I bought two of these devices. One of them was plugged into the FreeBSD 
 machine (as per previous post). The second one I was holding off on. But 
 today I inserted it into an OpenSolaris machine (NexentaOS_20061012), and am 
 experiencing almost EXACTLY the same problem.
 
 The kernel will detect the presence of it immediately, but trying to list 
 contents of /devices/pci_(_at_)__(_dot_)__(_dot_)__(_dot_)_ just leads to a hang. Until about 25 minutes or 
 so later when the kernel reports that the device is "online", and /devices 
 stops hanging (and rmformat etc works again).
 
 Someone correct me if I am wrong, but isn't the Solaris USB implementation 
 100% independent of the FreeBSD implementation? If so, and given the very 
 specific and IMO weird symptom of this bug, does not this indicate there may 
 be an actual bug in the device (even if it's not triggered in Windows or 
 Linux)?
