Dear all.
We're trying to develop a USB system, 2.0, based on a AT91SAM7S64 but we have some problems with the driver created by the NI-VISA application.
A few system
- OS, Windows XP (motherboard drivers updated)
- NI-VISA Driver Development Wizard version 4.1
and project details:
- a command interface
class: 0x2, sub-class: 0x2, protocol: 0x0
end-point address: 0x83, attributes: 0x3 , max packet size: 8 (0x8), Interval 255
- two bulk endpoints
class: 0xa, sub-class: 0x0, protocol: 0x0
end-point address: 0x1, attributes: 0x2, max packet size: 64 (0x40), Interval 0
end-point address: 0x82, attributes: 0x2, max packet size: 64 (0x40), Interval 0
We created the USB driver with the NI-VISA application and installed it following the instructions reported in USB Instrument Control Tutorial (http://zone.ni.com/devzone/cda/tut/p/id/4478).
Plugging-in the hardware and trying to complete the installation, the OS gives us the following error message:
It is impossible to run the device (Code 10).
Checking the Windows Device Manager, the hardware comes up with the yellow esclamation mark.
We've kept trying the procedure driver installation without any success.
(Please note that the installation with the original Atmel driver doesn't give us any problem.)
How is it possible to solve the problem?
Any hints or suggestions will be very appreciated.
Many thanks in advance.
Maurizio G.
