[App_rpt-users] Loosing TX

Mon Feb 10 21:39:43 UTC 2014

Hello Mike,

This is good information.  I looked at dmesg and saw there are 3 USB HUBs
(6 ports total: 2 on the side, 3 on the back and 1 internal).  I am using
the Asus Eee All In One machines.  I got a bunch of them free because the
touchscreen went out.  These were pulls as old POSs (Point of Sale, not the
other POS)  lol   These machines are great onsite for me because I dont
need anything extra other than a USB KB.  I have the two URIs on the back
of the machine and seems to be on the same hub.  I will make it out to the
site and move one to the side and check it is on another hub.  Hopefully
this will solve my TX problem.

Thanks for the input.
