As someone who's spent a good amount of time fighting VCC4's, here are
some ideas:
=20
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 adapter.=20

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.

Subject: [Playerstage-users] Help about ptz
Hi=20
I have connected my PTZ canon VCC4 on usb port on my laptop (
using a mini-din 8 pin ->serial cable and then using a serial->usb
adaptor)=20
But I have a problem to use Ptz with playerv. When I subscribe
the device with playerv, I can command ptz for only few seconds and then
the led on camera becomes red and I get this error message:
"SendAbsPanTilt errored. bailing"=20
After then, ptz remains in stop status even if I try to command
it with playerv.
Somebody can help me ?

playerstage internet site. why ?
