Greets,

I've got a 4900 that's posing a few problems for me. I've had a pair of these for about 6 months now and they worked great as modems on my old portable machines. The data connect between phone and USB port was at 115K and throughput was reasonable.

That changed however with the new computer I got. I installed the drives in the same fashion as with any setup I had, but the phone will only connect at 28.8K --- which is killing the OTA transmision speeds.

The only difference between the old 'puters and new ones are that the new machines have USB2 ports, rather than the USB1.1 ports.

I've got a call into Sanyo to see if they're aware of this, but don't hold a lot of hope out that they'll jump to fix this problem.

The phones, both of them, work fine on the older USB ports, but not with USB2. Software rev of the phones is 1.056 --- and understand that there's a 1.057 rev available. Not sure that this would fix it, but maybe so.

Anyway --- anyone have luck connection to a USB2 port with their 4900, and if so did you have to mess around to get it to work at something other than 28.8K.

Thanks

just got off the phone with Sanyo, and as I thought they passed the buck to anything that moved -- Sprint, Futuredial, the guy down at the corner that looked at me as I passed by.

Anyway --- if anyone's got any ideas I'd love to hear them.

I assume you were the one who posted this solution to alt.cellular.sprintpcs:

For those who have been working to get a 4900 to work on a machine with USB2 ports there's a fix!!

Working with the fine folks over at Futuredial (Byron, via email) we discovered that the new XP drivers for the 8100 work with the 4900. The new drivers address a communication problem between the phone and the computer with USB2 ports which limited speeds to 28.8K. Those speeds raced to 230K (yes, I know that's between the phone and machine -- not OTA) after installing the 8100 XP drivers.

The drivers will reconfigure your "Sanyo 4900" modem to a "Futuredial CMDA" [CDMA] modem. This means that if you're using a straight XP connectiod [connection] you'll have to repoint your modem setting to get it to work. Other than that it's painless.

A true tip of the cap to Byron and Futurdial --- they got after the problem and got it fixed.

I've no problems with USB 2.0 w/ mine as far as data connection speed, however after a time of being connected, the network seems to stop responding, and the phone seems to lock up. I disconnect from the software and it will sit for up to 2 minutes before it goes back to the main connection screen... sometimes the phone just locks and I have to remove the battery and reinsert it. Would this driver fix this?
