[argyllcms] Problem accessing HCRF probe

Ok, I'm trying to use the HCFR DIY probe, but it fails:

$ dispread -D -v /tmp/DisplayA
Number of patches = 100
Setting up the instrument
hcfr: About to init coms
hcfr: About to init USB
icoms: About to set usb port characteristics
icoms: About to open the USB port
icoms: USB port needs opening

icoms: Write_Read Write failed - returning 0x2000

The instrument can be removed from the screen.
icoms: delete called

Dispread: Error - dispread failed with 'Instrument Access Failed'

It is not a permission problem, because solved it (udev rule). And there are 
no messages in /var/log/messages...
