The microscope automation controllers from Prior Scientific,
specifically the OptiScan2 controller (the only one I have access to at
present) use a Cypress CY7C64013-SXC for USB->serial conversion. I've
tested the following patch against drivers/usb/serial/cypress_m8.{c,h}
with success (it just adds the vendor-id and product-id), and I was
wondering if it could be added to the kernel?

Prior Scientific OptiScan2 controllers contain a
Cypress CY7C64013-SXC chip for RS232 conversion,
which can be served by the cypress_m8 device driver.
