I'm trying to get the FT245RL chip to work but am running into an issue where it is not successfully connecting to my computer.

I also have a separate device which also uses the FT245RL chip which connects correctly so I know that it is not an issue with my computer.

When my device is connected dmesg spits out

[1174250.282775] usb 2-1.3: new low-speed USB device number 108 using ehci-pci

When plugging in the working device (that wasn't designed by me) that uses the RT245RL it says that it is a full-speed USB device. I know that there is a program which you can use to write the manufacturer and serial number so maybe you can also select wether it's low speed or full speed?

From trying to research I see errors that are somewhat related to this are due from not having sufficient power going to the usb device. Maybe the low-speed issue is some fault with my power line.

I've tried continuity checking all the connections from my schematic to make sure everything is correct.
