[argyllcms] Re: EyeOne Rev B. doesn't walk

Maybe someone else who runs Eye One Match on a Mac can comment on
whether Argyll can see their instrument ?

Of course only one application / driver can access the instrument at the same time. As long as e.g. eye-one match runs and uses the instrument, argyll or any other application has no access to the instrument.

There were some issues with old Gretag drivers that didn't release the instrument after quiting, but with up-to-date drivers this should be no problem.

Even with these old drivers, the instrument should work with argyll immediately after reboot (before any other application tried to access the Instrument).

As long as Eye-One Match 3 is running, "spotread -?" returns:
Read Print Spot values, Version 1.0.2
[...]

 -c listno            Set communication port from the following list (default 1)
    1 = 'usb:/bus29/dev0 (GretagMacbeth i1 Pro)'

and "spotread" returns:
spotread: Error - Configuring USB port 'usb:/bus29/dev0 (GretagMacbeth i1 Pro)' 
to 1 failed with -9 (usb_set_configuration(SetConfiguration): device not opened 
for exclusive access)

immediately after quitting Eye-One Match, spotread works as expected:

Spot read needs a calibration before continuing
Place the instrument on its reflective white reference Serial no. ...

(eye-one rev A, MacBook Pro, OS 10.5.4)

I see the eye-one in the system profiler as follows:
eye-one:

  Version:      1.01
  Bus Power (mA):       500
  Speed:        Up to 12 Mb/sec
  Manufacturer: GretagMacbeth

  Vendor ID:    0x0971
