A new installer for Mac OS X 10.3.x Panther resolves an issue with our USB modems when working through a hub.

This software needs to be installed ONLY if the customer is having trouble with our modem when connected to a USB hub. This problem does not show up when connected directly to the Mac.

Here is the software description:

This software works around a known problem in Mac OS X 10.3 Panther that affects bus-powered USB CDC modems connected to a USB hub.

Multi-Tech models affected by this software include the MT5634MU (MultiMobileUSB family), MT5634ZBA-USB (MultiModemUSB family), and MT5634ZBA-USB-V92 (MultiModemUSB family).

The installer file is found here:


The version number for this software is 1.0.0. This will only install on Mac OS X 10.3.0, 10.3.1, 10.3.2, 10.3.3, and newer (in other words, 10.3.x). The previous versions didn't have this problem.
