Tadellos mit Win7 64bit und HP Laserjet 4050
Die Kombination Windows 7 Ultimate 64bit und HP Laserjet 4050 aus dem Jahre Schnee funktioniert einwandfrei. Nach Verbinden des Kabels wurden alle Treiber automatisch installiert.

Will work with Lenovo Yoga 910
Many of these adapters have questionable compatibility. They will work for one device and not for another. I am writing this review to sat that this device will work the Lenovo Yoga 910. If you have this laptop, get this.

Good active converter.
Using this to communicate with PIC micro-controllers using a CCS serial port monitor that is built into their compiler and it is working perfectly. Install the drivers and the program detects the comport properly. The only thing that I don't like about it is that it needs to install the drivers every time you plug it into a different usb port and each usb port is then a different comport, so if you switch usb ports remember to change the setting in you serial port monitor to make sure that you are reading the correct port. Other than that it is solid for a solid price.

good USB to Serial cable
Have been using this Serial to USB device for a good few years now and has served me well . I think i recall once or twice having issues with the drivers over the 4 or 5 years but it was easily solved by going to the TRENDnet website and updating the drivers. no complaints and a solid product.

Excelente
Para el que puso que no sirve es porque no instaló los drivers que se requieren, a menos que tengas tu PC lista para su uso. Me sirvió muy bien, el precio es realmente nuevo ya que eso cuestan aquí con una calidad muchísimo menor.
