Subject: usbserial speed limitations ?
Date: Thu, 4 Feb 2010 09:58:55 +0100	[thread overview]
Message-ID: <20100204095855.10993d1a@tux.DEF.witbe.net> (raw)

Hello,

I'm about to start working with a new USB 3G+ modem (Novatel Wireless
M996D), details :

  Product ID:	0x5023
  Vendor ID:	0x1410  (Novatel Wireless, Inc.)
  Version:	 0.00
  Speed:	Up to 480 Mb/sec
  Manufacturer:	Novatel Wireless, Inc

>From the manufacturer web site, regarding the installation, I can read :

"Maximum connection speed is limited by the current generic usbserial
driver to approximately less than 500kbps."

Is there really such a speed limitation in the usbserial module/driver ?
This modem is HSPA+, which should allow a theorical maximum downspeed of
20MBps, not 500kbps...

The machine intended for such use in 2.6.28.x. Is there any chance to have
something better with a newer kernel ?

Any help / hint appreciated...

Regards,
Paul
