A quick test with my Katana on a Pi-3B and latest 8.3.6 version of moOde which uses 6.1.21 kernel and no issues whatsoever.
Your USBridge Signature uses a Pi-3B+ processor which should also work just fine with Katana.
The Allo I2S driver problems are as follows:
1. Katana I2S driver load fail on Pi-4 and 6.1.y kernel
2. Boss 2 I2S driver not working on kernel < 6.1.35
The USBridge Signature ASIX driver controls the Ethernet and USB interfaces and is not related to the I2S DAC drivers mentioned above. The ASIX driver is part of the stock Linux kernel but Allo made an enhanced version of it that bumped the max bitrate it could handle so DSD512 could possibly be supported.
This enhanced Allo driver was never accepted into the Linux kernel so our project compiled and included it up until recently where it wouldn't compile on the 6.1.y kernel. Allo was not able to provide tech support for it anymore so we dropped it as abandoned code.
The stock ASIX driver that ships with the Linux kernel works just fine on USBridge Signature USB interface for PCM rates up to 705.6 kHz and DSD rates up to DSD256.
