digiclsb.sys BSOD


We have a computer on Windows 7 Professional x86 that is getting consistent BSOD errors caused by the digiclsb.sys driver. The driver is from 11/6/2007, and I believe it might be outdated.

Where can I get an updated version of this particular driver? The hardware ID is VEN_114F&DEV_0028.

This BSOD is causing us not to be able to probe our buses and I need to try and resolve this issue as soon as possible.

I have attached a text file output from BlueScreenView detailing the BSODs.

Thanks in advance,

update your driver. 9.x I think is the most current:


Which of those do I download? There are a few of them on the link you provided.

I have a ticket w/ support. They gave me a driver, everything worked until this morning, now the BSODs are even worse. They appear every time shortly after the Windows 7 log on screen. Disconnecting the serial port resolves them, but clearly not a solution.


Not to bump an old thread but I’m having this exact problem. Was there ever any update to this? I am running win7 x86 with a digi neo 8 and my system will crash whenever I have a device connected using 115kbs 8 n 1
