trouble setting two identical usb mics

At the office we bought three identical Blue snowball usb microphones to do live interview recordings on separate channels, but when connecting at least two mics to the mac, only one is listed in the input sound panel. System profile recognizes both, but only one is listed, rendering it impossible to group them as an agregate device (what we are intending to do).


I've already repaired disk permissions and rested de PRAM and VRAM, but still getting the same result.

MacBook Pro, Mac OS X (10.5.8)

Blue solved it. The system recognizes all the mics, but as they have the same credentials, they aren't listed separately in the audio inputs available, so the factory must fix something in the firmware for them to be identified as different devices. If you're on the US, just mail blue, tell them about the problem and they'll ask you to send them the mics so they can reset the firmware.


For us outside, the fix was made by the vendor, who got the firmware package from Blue due to mail comunications we got with the brand. Today they work nicely as they're supposed to, sitll can't get the 3 work alltogether at the same time, when connected to our hub the got way too much ground noice, so we're thinking it can be the hub itself, which does not have its own AC input, and depends on the usb port power to enable the 3 devices... ¿any suggestions on that?
