There is an update available for the Treo 800w for USB and battery charging.  It is designed to address the following:

USB

If your device fails to detect any of the in-box USB accessories such as the power adapter, headset or sync cable, this update will resolve most of the detection issues.

Battery charging

When plugged into the charger, the device may not charge a completely discharged battery. This scenario is most likely to happen if you leave a dead battery for a few days before trying to charge it in the device.

If the device will not turn on to install the update, you should “trickle charge” the battery by connecting your device to a PC via the USB sync cable. The device will charge slowly by using the PC’s power. When the device’s battery indicator shows 25% charged, you can proceed to install the update.

This update is highly recommended for all Treo 800w devices.

Effect of resets

If you install the Treo 800w USB and Battery Charging Update and perform a soft reset no action is necessary. The Treo 800w USB and Battery Charging Update remains installed after a soft reset.

If you install the Treo 800w USB and Battery Charging Update and perform a hard reset, you will need to re-install the Treo 800w USB and Battery Charging Update.
