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: About to open USB port 'usb:/bus0/dev18 (Colorimtre HCFR)'
icoms: USB port is now open
icoms: Clearing any USB errors
icoms: usb port characteristics set ok

hcfr: Doing break
Break done, ICOM err 0x0
hcfr: About to init instrument
hcfr: About to read firmware version

icoms: Write_Read called with '\377'
icoms: About to write '\377' ICOM err 0x0
icoms: Read called
icoms: About to return read '' ICOM err 0x2000
icoms: Write_Read Write failed - returning 0x2000
hcfr_command failed
hcfr: Error with getting or version of firmware
The instrument can be removed from the screen.
icoms: delete called
icoms: closing port
usb_close_port() 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...
