someone who's spent a good amount of time fighting VCC4's, here are some
1) First try controlling the camera with either Canon's
windows-based software (vcc4ctrl.exe, from the canonusa.com site), or some other
software with built-in VCC4 support. This may indicate whether the issue
is with the cable or USB adapter, or with the Player driver. The vcc4
serial comms are finicky. The cable requires the RS-232 hardware
handshake lines not often used anymore in RS232 comms, and
USB->serial adapters often muck up some things, especially timing
issues. If VCC4ctrl.exe works, then the problem is probably
either the Player driver or the linux driver for your USB->serial
2) Don't know why the vcc4 documentation (but not
source) has been removed from 2.0.3 and cvs. I've had a lot of issues
with the Player vcc4 driver, so I wrote my own as a Player plug-in driver.
At least for me, it's been more stable and uses more of the capability of the
VCC4 (speed, etc) than the stock driver. I've been meaning to put this up
on the Player Wiki. If 1) doesn't help you, I can revisit packaging my
driver up for public consumption.
