This is rather an enhancement request than a bug report.

When executing a sign off command, jtagmkII and dragion do a hard reset by default. This also implies re-discovery of the usb device. While this isn't a big problem when attaching those devices to your computer directly, it becomes a big problem when using avrdude in a Virtual Machine.

There, on every sign-off, the hosts detects the removal of a USB device, signals it to the guest, then detects a new USB device, and signals it to the guest. This can take up to 5 seconds.

Both devices offer the possibility to modifiy the behaviour of sign-off to a "soft reset", thus avoiding that lengthy cycle. The appended patch forces this by passing "-x soft-reset" on the command line.
