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
|

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
|
||||
check.
|
||||
NB: async_unlink=0 would cause Oops. It remains just for
|
||||
debugging purpose (if any).
