To obtain more bandwidth you can either:

a) Remove other devices are on the shared USB controller.

- or -

b) Close applications that are using devices on the shared USB controller.

- or -

c) Change the device that needs more bandwidth to a different less impacted USB controller. With most current PCs, there are multiple USB controllers, although it may not be obvious as to which USB connections are on which controller. Often when a system has both front and rear USB connections, these are supplied from different controllers.
