I frequently use a Belkin USB to serial adapter to connect to router console ports.
My point was just that it is within SecureCRT's abilities to detect that the device is gone and display an appropriate error message, which I'm sure you'll agree is a better response than getting stuck (probably in the windows equivalent of an iowait state) waiting for the device forever. We already established this much in the first post.
I'd put this in the Don't Do This category. This is why Windows has the Remove Hardware tasktray item - so that software can be gracefully notified of device closure. It is not appopriate to remove hardware when software is still using the device. The fact that it works from some USB-to-Serial devices does not make it supported in general.
#Usb secure adapters driver#
The driver should close the instantiation, and this leaves SecureCRT in a pickle - it probably wants to read (or write) more data from the device, but the device is gone. Unplugging the USB cable requires sending a device Close call, since the device is no longer in use. In the USB to serial connection, the mapping is made at the OS driver level to map the USB device to the serial device. So unplugging a cable (although not truely supported by hardware) from an active system is no real problem.īut a USB device when connected to a system has to create and map the device. Serial devices are opened and closed, and by nature, do not just disappear. This is most likely not SecureCRT/CRT's problem.
