vid - Vendor ID for the device (optional)
pid - Product ID for the device (optional)
nrpacks - Max. number of packets per URB (default: 8)
async_unlink - Use async unlink mode (default: yes)
device_setup - Device specific magic number (optional)
- Influence depends on the device
- Default: 0x0000
This module supports multiple devices, autoprobe and hotplugging.
NB: nrpacks parameter can be modified dynamically via sysfs.
Don't put the value over 20. Changing via sysfs has no sanity
