This is the error shown in 'dmesg' log

ugen0.2: <Prolific Technology> at usbus0
uplcom0: <Prolific Technology PL2303 Serial (ATEN/IOGEAR UC232A), class 0/0, rev 1.10/3.00, addr 2> on usbus0
uplcom0: init failed!
device_attach: uplcom0 attach returned 6
uplcom0: <Prolific Technology PL2303 Serial (ATEN/IOGEAR UC232A), class 0/0, rev 1.10/3.00, addr 2> on usbus0
uplcom0: init failed!
device_attach: uplcom0 attach returned 6

Scenarios:

 1. kldstat -v | grep  uplcom shows
      303 uhub/uplcom
 
 2. uplcom_load="YES" in /boot/loader.conf
      with a reboot

In both the scenarios, 'dmesg' shows the same error.

On re-attaching the device, the following error is shown.

usb2_alloc_device:1574: set address 2 failed (USB_ERR_STALLED, ignored)
usb2_alloc_device:1612: getting device descriptor at addr 2 failed, USB_ERR_STALLED!
ugen0.2: <> at usbus0 (disconnected)
uhub_reattach_port:417: could not allocate new device!

The output from 'usbconfig dump_info' shows 
ugen3.1: <UHCI root HUB Intel> at usbus3, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON
ugen4.1: <EHCI root HUB Intel> at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON
ugen0.1: <UHCI root HUB Intel> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON
ugen1.1: <UHCI root HUB Intel> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON
ugen2.1: <UHCI root HUB Intel> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON

The 'dmesg' extract of USB is as follows:

usbus0: 12Mbps Full Speed USB v1.0
usbus1: 12Mbps Full Speed USB v1.0
usbus2: 12Mbps Full Speed USB v1.0

uhub0: <Intel UHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus3

uhub1: <Intel EHCI root HUB, class 9/0, rev 2.00/1.00, addr 1> on usbus4
ugen0.1: <Intel> at usbus0
uhub2: <Intel UHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus0
ugen1.1: <Intel> at usbus1
uhub3: <Intel UHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus1
ugen2.1: <Intel> at usbus2
uhub4: <Intel UHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus2

Here is the system information.
