A USB Cable with Ferrite Chokes on, will most likely solve your problem

Having spent far too many years doing EMI/RFI compliance work on a wide range of consumer products, I can tell you that chokes are extremely unlikely to make any difference at all in the reliability of a USB device. The purpose of ferrite chokes is to reduce emissions radiated FROM the cable itself. The frequencies they act on originate within the PC or device itself, not the relatively low frequencies of the USB devices. They do essentially nothing in terms of suppression of noise induced INTO the cable from external EMI/RFI, which is clearly the problem here. Also, chokes operate on VERY high frequencies - typical hundreds of MHz. FAR beyond the operating frequency of USB.
