Jim Dixon and I have had disapointing results with USB hubs during the testing of USB fobs with them. We don't know why they don't work properly and we don't have the time to figure it out right now. There may be hubs which work just fine, but we just don't know as the root cause of the problem has not been uncovered. If Steve Henke W9SH knows something I don't them maybe he should speak up on the list.

Why can there be no USB Hubs?
I have two systems in development right now that will both require
hubs to gain enough ports.
The adding one at a time and keeping them in the same location is the
reason to use the URI's and add eeproms. Has anybody actually
utilized the eprom functions using a URI and Asterisk?

I remember a few years ago when I bought my first iMic to interface with Apple's iBook that didn't have a microphone... At that time they actually qualified certain USB hubs as audio compliant. I'm not sure if they still do that or not, but there was (and likely still is?) a huge disparity in performance and it seems like audio was more severely affected than less noticeable hiccups in the data transfer rate on a hard drive or something.
Just my $0.02.

David,
First off, I just learned something myself about adding extra radio
ports using USB fobs: They must be added one at a time.
Second, there should be no USB hubs between the FOB's and the PC's USB
ports.
Finally, what type if linux install is this? ACID, EVB, custom?
I'd suggest restoring the configuration back to one radio port get that
working, then add and tune the ports one at a time.

Hi Roger & Steve,
Well, I'm making progress. I've noticed a couple more things I thought I'd

access 2 of the 3 URI's I have attached to the PC....Initially, I only
plugged 1 URI in and couldn't get it to work at all (though the green LED
was blinking)....Then, when I plugged in a 2nd URI, the first started
working (with my TKR-850)....Today, I found that the second wasn't

both of the original 2 are now working. Strange.....Perhaps this has
something to do with udev? Anyway, this isn't holding me up at the moment.
The second issue is more troublesome. I can't get the repeater to link to
the remote base....When I issue the connect command: *2(node number), the
controller says it's linking both on the console and verbally. But, then
it seems to hang totally with the TX enabled from the end that received
the commands. I've tried this both ways--repeater to remote base (commands
from the repeater) and vice versa. I end up having to kill -9 the asterisk
process to regain control--"stop now" from the asterisk console
hangs...This should work, right?
Thanks in advance!
