Default 8100 USB cable the same?

Please Login to Remove!

Hello,

I just moved to a 8100 Pearl from my 8700c. I have my USB cable setup on my office desk to a make-shift cradle I used from my old 7290; I've been using if for my 8700c.

I didn't bother changing to the new USB cable that came in the Pearl box, instead just left my previous cable from the 8700c. Are the cable technically different? The previous one plugs in just the same.

Why I ask is because after I plugged in my pearl to the old cable, to charge it, a short while later I saw a message on the pearl screen stating something to the effect of ... "not enough power to charge the batter".

The other end was securely plugged into the computer so no issue there.
I then switched over to the new cable, never got the message, but it seems really really slow to charge, compared to how fast my 8700c would charge.

Is this just me or anyone else seeing this issue?

Thanks,
Eric

just install the drivers/software that came with the 8100 on your machine. should clear up your not enough power issue... did for me!

The Linux 2.6.16 (?) kernel has limited the USB 2.0 power so that no device can draw more than 100ma on an unpowered hub. On my Ubuntu 6.10 laptop (2.6.17 kernel), I am unable to charge the Pearl on any of my ports.

ya, my install was done on a windows machine so I can't say for sure what will help the OP.

Guess I didn't think to mention my OS.

Yeah, I'm a WinXP pro user. I have since done as suggested by toekramp, installed the drivers and such that came with the disk and I have not seen that error message again. I still claim that it charges really really slow; and I'm using same computer/OS as charged my 8700c.

Also, see next message for my next issue ... can't connect with Desk Manager.

Thanks,
Eric

The cable for the Pearl is a standard USB A to USB mini-B.

The 'Not enough power...' message is typically a missing driver problem on the computer. In those cases, the Pearl will still charge over the USB connection despite the message.

You are right. Power coming out of a USB port connected to the PC [as opposed to an unpowered hub] is way lower than the power from the BB USB charger. So charge times from a PC USB port is way slower than from the charger.

Sometimes USB ports on a PC have power fluctuations just as power coming from outlets. At times when I connect my Pearl to a PC USB port I get the error message. I simply disconnect and reconnect the cable. Sometimes I have to reboot. Other times I just ignore the message since I am using DeskTop manager and my intent is not to charge the phone via the PC USB port.

And yes, sometimes it's a matter of the driver from the BB disc not being installed on the PC. Could also be the port is defective on the PC, for any number of reasons, including driver issues.

IMHO USB ports are pretty crappy technology. They are not precision made and there are no manufacturing standards which has resulted in billions of defective or under-performing ports residing on PC's everywhere. E.g., I have three Dell desktops that I use at the office. On each there are 6 USB ports. On each, about two to three do not work. They are 2004 machines, so they are getting way old, but one would think the USB ports would still work. Maybe I got a bad run of USB ports Dell used that year.
