AnywhereUSB Plus coupled with Digi Remote Manager® protects your peripheral devices and gives you the security agility needed to keep your networks safe. Network engineers need to take proactive measures to increase the security posture of their network. Increase Security Posture and AgilityĪs a network of USB IoT devices expands, the risk of cyber attacks increases. Digi AnywhereUSB® Plus lets you readily manage a large volume of USB devices with minimal effort. You also need flexible methods to test, provision, confirm and resolve any connectivity issues related to scaled deployments of IoT devices. As a network engineer, you need a consistent, secure and cost-effective way to verify that your IoT infrastructure is configured correctly and fully operational as it continues to expand.
In the IoT world, the technological evolution is accelerating and expanding, which drives the need to continuously update deployed devices with new features and firmware. I seem to recall that this is (was?) especially a problem on Windoze, but I have not used that OS for years.Rapidly deploy, configure, secure and manage devices at any distance
This may lead to some problems such as your PC not recognizing the hardware properly. but the price of an EEprom is often too much for the cheap devices.
Usually this is done with an EEprom next to the USB Serial chip which has vendor and product ID's. Your PC may need a way to keep those devices separated from each other, and needs to be able to identify them properly. Then I connected 2 terminal emulator programs to 2 of the serial ports, and data was echoed from one terminal to the other.Īs said before, USB is a bit complicated, but using multiple USB to Serial dongles on a PC should work just fine. 2 serial ports turned up on my Linux box. I has hardware USB and 3 UsART's and I found a demo program on github to use all 3 UsART's through the single USB port.Ĭompiled & Flashed the program, and sure enough. Some time ago I experimented a bit with the STM32F103C8T6 aka "Blue Pill". You can stick all of your RS232 dongles into the same USB hub and it should still work. Just add another 2 USB Serial converters (for RxD and TxD) and put them in 2 USB ports of your 2nd PC, or plug it all in a hub or whatever. When you're only interested in capturing data from a USB Serial connection, then you can also simply tap the data on the serial side. Simple searches for USB sniffer / monitor / analyser also give plenty results for a few days of reading. I'm not sure, but there may be plugins for Wireshark to split the data on the OS level and make a copy. I'm not sure where your interests are at the moment.ĭo you want / need to debug the low level stuff, or do you only want to capture USB data? Sigrok also has a cli, and I think it's possible to only filter out the data that goes to the endpoints, and redirect that to the monitor or a file. I saw all that in "Pulseview", which is the GUI for sigrok. It was quite fun to see the effect of T-states, bit stuffing, checksums and a whole lot of other things moving over the wires. I've successfully captured a bit of low-speed (1.5Mbit/s) USB connunication with Sigrok and the EUR 5 "saleae" clones (CY7C68013A).įor Full-speed (12Mbit/s) you'll need better hardware then I have.
