FUSBH200-HCD is an USB2.0 hcd for Faraday FUSBH200.
FUSBH200 is an ehci-like controller with some differences.
First, register layout of FUSBH200 is incompatible with EHCI.
Furthermore, FUSBH200 is lack of siTDs which means iTDs
are used for both HS and FS ISO transfer.

These patches implement a modification of the USBTMC
protocol to allow operation with Rigol equipment. The usbtmc_read function is
modified so if the quirk is active, the TMC header is sent with the size of
the data as the whole size of the request. If the quirk is inactive, the TMC
request is sent once per bulk transfer and with size limited to the bulk
transfer size. In the case of the quirk, only the first response contains the
TMC header and the others are just data.

These patches implement a modification of the USBTMC
protocol to allow operation with Rigol equipment. Rigol requires that a
single TMC request to receive any buffer size and bulk requests to get the
data. The original algorithm sends a TMC request for each subset of the data
(a single USB transaction). The modification is only active for Rigol
equipment, vendor and product set is contained in the array usbtmc_id_quirk.
This patch creates the rigol_quirk variable and the arrays for the
idvendor and idproduct.
