I understand that the expression "polling a device" means that a device is repeatedly"polled" or contacted by the computer to determine if the device is ready to receive and input, pending the device's unreadiness to accept inputs while executing a prior or prior commands. So far as I know, the polling continues till the device is ready to receive an input/command.
I just recently acquired a microscope and a camera specific to that instrument from the same Seller, Amscope Corp. The camera is connected via USB cable supplied with the camera. I first connected it to my MacPrPro. According to the Seller. I must say that, in its sales website pages, Seller affirmed the compatibility of the camera with Mac systems but adding words to the effect that its instructions for the use of the camera with a Mac were not as complete as its instructions for the use of the camera with a PC. I loaded the driver from Amscope's CD and indeed discovered there were virtually no instructions, just a dialog box. The CD included a 150 pahe instructions manual obviously intended for PC applications but virtually nothing for Mac applications. Nonetheless, I succeeded in obtaining a very fine display on my Mac and printing some very fine photos.
I then tried another object in the vision field of the microscope but this time, the camera would not work. No error message appeared.
So, I decided to connect the camera to my Toshiba PC and immediately discovered a fine program of instructions easy to follow but I could not obtain a display, The first error message read: "Error during capture, please replug the device or try another USB port and try again."
My Toshiba has 3 USB ports. The Device Manager informs me the ports are USB and USB2 and informs me of their location in terms I do not understand (e.g.: .0003). So, I reconnected to each of the ports, first starting with the USB port connected to my printer and then trying the remaining port, to no avail. However, on right clicking, a "Properties"option appeared, telling me " "Still image capture Y", "Still image width 0:, and "Still image Height 0", "Video wdth 1280 and "Video Height 1024."
This information seems to contract the error message...After a few more clicks, the following message appeared:
"The Device has been polled out."
What does that mean?
How do I fix what it means?
At this point, I sent an email to Amscope but do not expect a full reply very soon.
Thank you for your help.
