DisplayLink configuration returns error message

I am attempting to configure my laptop to display on a USB-to-HDMI DisplayLink adapter (specifically the Sabrent USB-HRHD adapter) for a dual-monitor setup. The adapter works correctly out of the box in Ubuntu, so I imagine it should be possible to configure it to work in Arch. I found the DisplayLink wiki article detailing steps for setting up the device, but I am encountering an error message.

First, I blacklisted the old udlfb kernel module as the article dictates. I confirmed through lsmod that udlfb *is not* loaded and the udl module *is* loaded.

Second, I got the following promising output from 'xrandr --listproviders'"

$ xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x7b cap: 0x2, Sink Output crtcs: 3 outputs: 2 associated providers: 0 name:modesetting
Provider 1: id: 0x16d cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 0 name:modesetting

Third, I ran the next command 'randr --setprovideroutputsource 1 0', but it resulted in the following error message:

$ xrandr --setprovideroutputsource 1 0
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  35 (RRSetProviderOutputSource)
  Value in failed request:  0x7b
  Serial number of failed request:  16
  Current serial number in output stream:  17

Does anyone know what could be going wrong? How can I further debug this issue? I tried Googling, but didn't come up with much. Any advice is appreciated. Thanks.
