I'm still working on getting this newer prolific USB to Serial device going. I found a couple of patches, but they seem to be having trouble with the 2303 hack in usbserial. Any thoughts? >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> I bought a USB to Dual RS-232 cable that appears to integrate a USB hub, and 2) PL2303 devices. Here's the link to the device: http://www.coolgear.com/productdetails1.cfm?sku=USBG-2X232&catid=465,199&cats= I started out just connecting the device to an available port on my machine (Intel P4 with RHEL 3WS - 2.4.21-4.ELsmp), dmesg showed that it was recognized as 2 seperate PL2303 devices, and each seemed to be appropriately mapped to /dev/ttyUSB0 and /dev/ttyUSB1. I connected a dumb terminal to the port, and simply tried an #echo Test > /dev/ttyUSB0. The command seemed to hang, and never came back to the bash prompt. I spent some time reading, and found a bunch of patches for 2.4.21, so I downloaded the usb-2.4.21.patch.gz file, and applied the patch. However, I still am experiencing the same results. Here's the output of dmesg: hub.c: new USB device 00:1d.3-1, assigned address 2 hub.c: USB hub found hub.c: 4 ports detected hub.c: new USB device 00:1d.3-1.2, assigned address 3 usb.c: USB device 3
