I’ve got Blackberry Bold!

Maybe it’s a bit late to be excited to have Blackberry Bold now, but anyway I’ve got one because I had a bonus this week. I ordered it online and this morning a courier delivered it to my house.
These are a cradle, a charger, USB cables and screen protectors I ordered from Hong Kong before hand.
I pulled my SIM card off my Blackberry 8707h I kept so far, put it into the Blackberry Bold and turned its power switch on. After several initial setups, the main menu appeared and NTT DoCoMo network was captured.
One problem occured. I found there was no email settings so I couldn’t set up emails I had used on 8707h. According to manuals, it was necessary to log in to Blackberry’s website at blackberry.com to change PIN and IMEI into ones of the Blackberry Bold, as well as to send a service book to the new device. Doing so, three email icons according to the email accounts I’d used so far appeared on the Blackberry Bold’s screen.
I configured its WiFi settings so that I can use it over the wireless LAN in my room, and set up Bluetooth so as to send files to my Nokia smartphones. I installed Google Sync into it to synchronize contacts into Gmail’s ones. Other than them, I installed twitterberry, a news reader and other utilities to make it more convenient when commuting to and from office.
Now the setups are almost complete, except for one problem with USB connection to my PC. I installed Blackberry Desktop Manager on my PC running Windows XP and connected my Blackberry Bold to it with a USB cable, but nothing was detected. When I connect my 8707h with the same USB cable to the PC, it can be normally detected. Why? Windows XP problem? Or problems with settings of the Blackberry Bold? Please tell me why if you have any idea.

As for the USB problem above, I downloaded and installed Desktop Manager 4.7, and then connected my Bold into my PC. Then I found the message

USB Device Not Recognized
One of the USB Devices attached to this computer has malfunctioned and Windows does not recognize it.

appeared from the right of the taskbar. When I launched Desktop Manager, I see the message

Device connected (PIN): None

at the lower left side of the application. Then I looked over the list under USB (Universal Serial Bus) Controller in Device Manager, I saw “unknown device” for the corresponding device.
When I connected my Bold with its battery pulled out from the phone, the “unknown device” changed into “Blackberry smartphone” but in Desktop Manager status remained unchanged. When I put the battery into the phone, it turnded into “unknown device” again.
I formatted the whole of my PC’s hard disk and then re-installed Windows XP again because my PC had not been working well these days, and then installed Desktop Manager 4.7 again. I plugged my Bold into PC again, but nothing changed.
Because the CD-ROM attached with the phone when I bought it contained Desktop Manager 4.6, I uninstalled DM4.7 and installed the 4.6 from CD-ROM, but DM didn’t recognize my Bold.
This issue seems to be known worldwide, and I see several websites troubleshooting it, but I find no sites describing the complete solution.

When I connected my BB Bold via USB into a laptop at my office instead of the PC in my house, it successfully detected my BB, so I found out that it was just a problem with PC…. I don’t know why, but I’ve given up finding out because I can now synchronize data with my office PC.
