bluetooth: Add support for EP-B3536 USB Bluetooth adapter

From: Jack Murray <kernel@c0rporation.com>

This patch adds support for the EP-B3536 USB bluetooth 5.1 adapter based
on the 8761B chipset. The existing driver and firmware work fine for this
device from what I can tell, so this patch just adds the vendor/product IDs
for it to the supported device list.

Who manufactures that device? Is it Teledyne? 0x2550 is 9552 (decimal), 
and according to [1] that is Teledyne. Maybe, add that to the commit 
message.

Kind regards,

It's actually EDUP (https://www.szedup.com/) that make it, not Teledyne 
(unless there's some link between the companies that I couldn't see). 
I'm happy to add EDUP to the commit message though if that's not going 
to cause any confusion by the names not matching?

please send an updated version addressing the comments and include /sys/kernel/debug/usb/devices.

Regards

Marcel

Sorry I'd forgotten all about this as I actually ended up returning the 
device since it didn't have sufficient range for what I wanted it for 
anyway, so I can't include the /sys/kernel/debug/usb/devices output. 
Here's an updated commit though if it's ok to merge without that.

This patch adds support for the EDUP EP-B3536 USB bluetooth 5.1 adapter 
based
on the Realtek 8761B chipset. The existing driver and firmware work fine 
for this
device from what I can tell, so this patch just adds the vendor/product IDs
for it to the supported device list.
