CanoScan Lide 100 with new Mac


I'm trying to use an older CanoScan Lide 100 with my new Macbook Pro with the latest Catalina OS version. The drivers for this model are available only until MacOS Yosemite, but they worked nicely with my previous Macbook with Catalina until the Mac suffered a painful death a few days ago and they also installed without any errors on this Mac as well. However, this new Mac has only USB C connectors and the scanner has regular USB - mini USB cable.


I tried to use a USB C - USB adapter with the original cable. With that the Mac does see the scanner as it pops up in the Image Capture device list nicely. However, when I try to scan something, I get an error message saying this:


"Scanner reported an error. 

Cannot communicate with scanner for these reasons:

- Scanner is turned off

- USB cable is disconnected


Please check and try again



Are there any hints how this scanner could be used with a USB C only Mac? I believe that Canon probably doesn't support this environment, but if someone has any hints how to get this working, I'm more than happy hearing from you 😉






Your hunch about the hardare not being supported could be correct.


Are you using a good quality USB-C to USB adapter?  All are not created equal.  if the PIN outs do not match or if inferior product is used, a communication failure might occur. 


Apple products (as I'm sure you know) can also be finnicky about the accessories they work with.  I carry a few display and all in one adapters in my bag since i never know what I might need for presentations or connectivity.


Try installing the v4.1.4 ICA driver.  If this doesn't install or fix, (and it might not since its not certified for OS Catalina) it might be time for a new device.
