USB Driver Installation Recovery
The USB TriCoder uses two separate USB “drivers”: The HID driver provided
with Windows and the TRICODERUSB High Speed transfer driver provided
with the TriCoder. Which driver is active depends on the operating mode of the
TriCoder.
Driver installation is initiated when the TriCoder device (HID or High Speed)
attempts to attach to the host and the driver is not present (or incorrectly
installed) on the host PC.
Incorrect driver installation is unlikely to happen; however:
High Speed driver installation can be cancelled by the user and the High
Speed USB upload in the TriCoder will not function. The High Speed driver
installation is re-initiated next time the TriCoder is attached either before or
after a Windows restart (depending on the version of Windows). Recovery
from an error in installing the High Speed driver is at worst rebooting the
PC and re-attaching the TriCoder to redo the driver installation.
HID driver installation is usually automatic: windows pop up indicating the
new device and then disappear on their own and you’re done. In some
situations, the required files for the HID driver are not all found on the
computer and the user is prompted for their Windows CD. If the user
cancels
the HID driver installation at this point, the HID mode TriCoder
will not function properly and Windows
does not
automatically initiate a
re-install as it does with the High Speed driver. Control panel utilities
(varies with operating system) are required to re-install the HID driver.
Resolving incomplete, aborted, or incorrect
HIGH SPEED driver installation
This driver is provided with the TriCoder (included on the Utilities CD).
Restarting Windows and re-attaching TriCoder will often re-initiate driver
installation; if so, just follow the instructions and this time point the installer
to the TriCoder Utilities CD, (or if you have downloaded the drivers, to the
folder where you saved the download).
Assuming the drivers was partially installed, you will have to update the
driver manually following the below procedures:
