U2irda Mini 4 Mbps Fir - Usb Irda 20 Portable
: Linux is a different story. The OS has included IrDA support in its kernel for many years, making recognition possible in theory. In practice, a user reported in 2006 that a U2IrDA Mini was detected and shown in the lsusb output (with ID 07d0:4100 ). However, achieving full functionality, especially at 4Mbps FIR speeds, often requires finding the correct Linux kernel driver for the specific chipset (SIR, MIR, or FIR) and manually configuring the IrDA system. The stir4200 kernel module is a key reference point for this chipset.
: Some models support Linux and Mac OS 10.x, though newer Linux kernels (4.17+) have removed IrDA support, requiring kernel downgrades or recompilation. Common Applications Fast USB 2.0 Infrared Adapter up to 4Mbps - Coolgear
