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
