Cannot connect Garmin Nuvi 860 via usb - problem with "Read Device Capacities"

When connecting a Garmin Nuvi 860 via USB to a windows 8 or Windows XP guest running under a Linux host the connection with a Windows Device Manager "Device cannot start (Code 10)" diagnostic. Analysis of the host Linux USB trace and the guest Windows USB trace shows that the problem occurs after windows has sent a "Read Format Capabilities" command to the device.
I bounced the attached logs off the linux-usb list. This is what the gurus over there had to say.
It is clear from the log that VirtualBox is messing you up. The resets that the guest tries to do never make it out to the actual device. Nor do the Set-Config and Set-Interface requests. This may explain the differing reactions to the READ FORMAT CAPACITIES command.
The Garmin device isn't blameless either. After sending its 12-byte response to that command, it is supposed to halt the bulk-in endpoint. But it doesn't; it responds to the next transfer with a 0-length packet and _then_ halts the endpoint. Things go downhill from there and it stops responding, after which Windows gives up.
