Hello jyaron,
Based on the description of the issue, it sounds like it could be a USB 3.0 issue. A number of our customers with Dell PCs are able to use the BB60C after updating to the latest USB 3.0 drivers.
Here is the latest USB 3.0 driver from Intel for your hardware configuration.

Let me know if installing this resolves this issue. Ensure the BB60C is disconnected when updating, and it will require a PC restart.
Hopefully we can resolve this quickly.
Edit: Additionally, if you have any heavy duty anti-virus software running, you might try disabling it. Software like Norton or MacAfee have given us grief in the past.
Regards,
A.J.
