Fwd: USBConfigureInterface error 2 -50

Hi Paul,

Unfortunately, USB isoc is not implemented in Classic. Keep in mind that many things that touch hardware (like drivers) will not function in Classic. Most of the hardware layer that does exist is shimmed through to the Mac OS X layer.

The best workaround is to get a native Mac OS X driver working for your device. :-) Alternatively, you can file an enhancement request at <http://bugreport.apple.com>.

Sorry to break you the news,

Hi Garth,

Yes it does.

Hi Paul,

Does your device have isoc endpoints?

My OS9 driver works fine when used with OS9.1-OS9.2.2. But when I use
it in
Classic mode on OS10.1, I get an error that does not allow the driver to
configure the device correctly. When the driver calls
USBConfigureInterface
to complete the process of selecting an alternate interface, I see this
error in the log:

USBConfigureInterface error 2 -50<< 

My completion routine detects error -50.

MacErrors.h says this is a paramErr. But since the driver operates fine
with OS9 running "native" I am suspicious of OS 10.1.

Any advice?
