FT232BM or FT245BM device hangs randomly during operation
under Windows 98

This is not caused by the driver, but is a hardware compatibility problem. Some newer USB 2.0
hubs and host controllers can be susceptible to noise and can cause random device failures. This
can be overcome by fitting 47pF capacitors to ground on the USBDP and USBDM lines on the USB
connector side of the 27

W

series resistors.
