Device Setup Class Question

Dear All,

We're developing a scientific instrument which communicates via USB to
transfer experimental procedures from the PC and stored results to the PC.

Can anyone advise on what Device Setup Class this should go into? I can't
see one but creating a custom setup class seems a like a big step for this
one product (all the others are major groups of devices)

We are using the Jungo system to do the comms, so we don't have a separate
driver as such, just an inf file to tell Windows to use the Jungo driver when
our instrument is connected. The instrument uses interrupt-mode transfers
only.

Thanks for your help.

How much data is transferred and how fast should it be.
Only dumping collected data to the PC without time restrictions is
easiest implemented as HID device. No drivers needed.
A simple command protocol can be created like writing a report to the
device and the device disgorges the data.

Dear Robert,

Thanks for the rapid reply! If I was starting today, I certainly would use
the HID support built into the OS. However in reality I can't go back on
decisions that have been made.

As far as I can see, I _should_ use a custom device class since this device
doesn't fit any of the ones listed - if that is the case should I be naming
it according to the type of thing it is, or my company name, or the
instrument's brand name?

create a custom class, it is not that big of a deal and the only ones who
really see it are users who open device manager.

It just seems like it should be a big deal - for example all imaging devices
ever made are one class, and our instrument on its own is one class!

Anyway, thanks, that has answered my question, I will use a custom class.
