<p dir="ltr">You're going to have to start going backwards with kernel versions to find one without issues. Then read change logs to find who changed foo on the USB stack and write them directly with your corner case. Be ready to compile kernels with patches to test.</p>

The version of hplip I'm running is 3.14.3-0ubuntu3.2<br>
<br>
Jim,<br>
The kernal version I'm running is 3.13.0-24-generic.<br>
<br>
While I'm willing to update my hplip version, the USB issues bothers me more.<br>
<br>
Suggested approaches?<br>

Ah. I recall these systems were having issues with USB earlier. Have you<br>
changed kernels? Don't recall results of live CD alternate distro tests.<br>

I seriously doubt hplip is the root problem. The more I work with this<br>
the more I am inclined to think it's a USB problem. It doesn't seem to<br>
matter which USB socket I plug it into, it doesn't show up under lsusb,<br>
or lshw. I've been having flakey "permission to mount" issues with<br>
thumbdrives, too. None of these issues appear on any forum I am<br>
familiar with.<br>
<br>
More suggestions?<br>

I had the same issue with a Ubuntu box sometime ago. The problem<br>
was a<br>
broken hplip package (did you have an update done recently? ). The<br>
solution was to download the package from the HP site and<br>
install it.<br>
Others reported that rolling back to an older version would also<br>
work. I<br>
did not try that.<br>

I have three systems, one running Linux Mint 13 (32 bit), and<br>
two that are running Linux Mint 17 (32 bit). I have a<br>
USB-attached printer (HP 895Cse Desket) that these system<br>
suddenly ceased to recognize. Attempting to delete the printer<br>
definitions and re-install it doesn't work (the printer is not<br>
recognized as being attached to the system and, therefore,<br>
available).<br>
<br>
What has me confused is that my Dell Inspirion 1525 laptop,<br>
running Linux Mint 17 (64 bit) does recognize it. I can't<br>
convert my other systems to 64 bit because their hardware won't<br>
support it.<br>
<br>
What am I missing?<br>
