That's not good. The command should complete normally. You seem to be missing
about half the data mine displays for this type of device. I'm no USB device
expert, but I'd guess the root of the problem is the bluetooth adapter itself.

My listing starts like this:

Bus 004 Device 002: ID 050d:0121 Belkin Components F5D5050 100Mbps Ethernet
Device Descriptor:
bLength 18
bDescriptorType 1
bcdUSB 2.00
bDeviceClass 224 Wireless
bDeviceSubClass 1 Radio Frequency
bDeviceProtocol 1 Bluetooth
bMaxPacketSize0 64
idVendor 0x050d Belkin Components
idProduct 0x0121 F5D5050 100Mbps Ethernet
bcdDevice 1.00
iManufacturer 1 Broadcom Corp
iProduct 2 BELKIN BLUETOOTH USB ADAPTER CL. 1
iSerial 0
bNumConfigurations 1


and ends with:

Interface Descriptor:
bLength 9
bDescriptorType 4
bInterfaceNumber 3
bAlternateSetting 0
bNumEndpoints 0
bInterfaceClass 254 Application Specific Interface
bInterfaceSubClass 1 Device Firmware Update
bInterfaceProtocol 0
iInterface 0
