USB Expansion Card for Dell R710 Server

Hello.  I'm trying to plug in 4 of these:


Into a Dell R710 Server : http://www.dell.com/us/enterprise/p/poweredge-r710/pd

I'm using Linux.

When I plugin the timers to the provided USB ports in the front part of the server I'm only seeing one of the USB Sangoma Timers.

When I plug them into the back 2 USB ports, I can see both timers.

I believe the front ports are using a shared BUS.

Do you think if I purchase this card:


All (4) USB UT51 Sangoma Timers will show up as separate devices in linux?

Let me know if you have any questions by responding below.

Hard to know for sure, but chances are it will support at least 2 of the Timers, that and the 2 in the back should suffice.

I hope this helps !

ntp isn't fast enough.  I'm dealing with very precise timing on these cards.

NTP is not granular enough.  This is internal clock timing for a phone system.   No answer found.
