Hello,
I use USB TC-08 with my own program calling the supplied DLL. I use the following call sequence (in pseudo code):
usb_tc08_open_unit
usb_tc08_get_formatted_info
usb_tc08_set_channel
while (stop == FALSE)
{
usb_tc08_get_single
}
usb_tc08_close_unit
Everythings works fine for long periods of time. I can also stop and restart the program, and everything works. The problem arises when I stop the program for about 1 hour or more and restart after that. At that time, the driver cannot find any USB TC08 units attached. I have to unplug the USB cable and plug it back, and after that the program starts working correctly again.
What can be done to avoid this behavior?
I run the program under Win 2000. The module response to get_info quiry is:
Driver version: 01.01
Picopp.sys version: 01.08
Hardware version: 1
Unit variant: 3
Batch and serial: FJL90/133
Calibration date: 09Nov04
The DLL that I am using is USBTC08.DLL, its size is 112 KB (I don't know its release version).
Thank you,
-- Sergey Liberman. |

Hi
Thank you for your post.
Do you have the same problems if you use our software?
Does it report in the device manager?
I cannot immediately think of any reasons as to why this could be happening, I would suggest that it might be easiest to keep re-connecting the USB lead when you want to use it.
If you experience the same problems when using our software then please let me know.
Best Regards |
