What's in the box

  • Serial adapter
  • Product Description

    Features a Prolific PL-2303HX Rev D chipset for the best combination of performance and wide driver support. Drivers available for Windows 11, 10, 8.1, 8. 7, Vista, XP, macOS/Mac OS X 10.6 and later; open source drivers included in Linux kernel 2.4.31 and later. Windows 7 - 11 automatically detects and guides driver install without disk. Not compatible with ARM-based Windows (MS Surface). Compatibility Works with devices with RS-232 serial ports like: other PCs with RS-232 ports, Bluetooth serial adapters, PDAs, GPS receivers, routers, firewalls, modems, printers, embedded character displays, scan tools, sonar units, embedded boards, etc. Works with software like: HyperTerminal, TeraTerm, WinDBG, all open source serial software on Linux, etc. Connector compatibility note The DB9 connector has fixed female side screw in connections. For connecting to a device that also has fixed female side connectors an inexpensive DB9 Female/Female Mini Gender Changer (Coupler) will be needed. Genuine We use only genuine Prolific chips. There has been a problem with some USB serial adapters using clone chips not actually from Prolific. These adapters will not work with Prolific's latest drivers, thus won't have support on recent operating systems like Windows 7 - 11. Because we only use genuine Prolific chips, our adapter is always compatible with the latest drivers from Prolific.

    I first want to note that this adapter looks nothing like the one pictured. The aesthetics make no difference with regards to its performance, but I was honestly a little put off by this. I've somehow misplaced my old adapter and was hoping to get one identical to what I had before. The plastic clamshell housing unique among these cables and I was surprised to get one that looks more like an injection molding. It bares the same 'plugable' name, at least by a cheap stick-on tag.As for its function, it works great and it does take the Prolific driver, which is most important to me. My disappointment is really superficial, because this cable will do the job, but how hard is it to update your produce picture? There is absolutely no resemblance between the two cables.

    Reviewed in the United States on November 27, 2013
    I'm a network engineer and work with older Cisco equipment that often requires me to use a serial connection to do the initial configuration. I had to replace my old Dell laptop after it was stolen and the new one did not have a serial port. We have used this same USB to Serial adapter at work with nary a problem so I was psyched to find one for less than what the boss pays.

    One observation. The unit comes with a driver CD and instructions to install the drivers before connecting the adapter to the computer. That might be true with XP or Vista, but Windows 7 will download a WHCL driver automatically as long as you have an Internet connection when you first plug it in.

    I have not had any compatibility issues at all. I have used it to connect to several different external modems and numerous Cisco routers, switches, and access points and it just works.

    UPDATE: I plugged it into my Vista Pro desktop and the drivers installed automatically. Works perfectly there as well. Will test on a Sony Flip Win8 on Christmas and report findings on that as well.

    UPDATE, Part Deux: Works fine on Win 8.1 and Win10. On my wife's Win8.1 Sony it took a couple of minutes to load the driver. On my upgraded Win10 Dell 4600 workstation it only took a few seconds to load the drivers.

    This is a great gadget. I had a couple problems with it, though.

    #1) The Amazon page says it's a female DB9, and it isn't. It matches the male connector found on Windows boxes. It was OK, though. I thought I needed a female, so I got what I really needed.

    #2) I'm working with 2 computers, a Dell 5414 laptop (Debian Buster) and a Raspberry Pi 3+ (Raspian Stretch). I'm trying to put the Pi on the Internet as a server. That's why I needed this adapter -- I need to talk to Juniper and Cisco routers and stuff, and the Pi has no (easily accessible) 232 port.

    Plogable's Linux dox say, essentially, "Plug it in." That works on the Pi which creates just /dev/ttyUSB0, but not on the laptop which creates ttyUSB0 through 3. And it makes ttyUSB3 the active connection.

    The way to deal with this, I found after several hours futzing with USB0 and talking with Plugable support, is to plug it into an already booted computer, type 'sudo dmesg' on a terminal, and read the last line. Linux notices the newly plugged in USB device and deals with it. But Plugable doesn't say anything about the possibility of more than one ttyUSB entry in /dev anywhere, and your machine might do something unexpected, like mine did.

    Plugable support, BTW, is a delight. Very competent, responsive, and helpful.

    If you are an IT professional looking for a USB-to-RS-232 Console adapter, look no further. The Prolific PL2302HX Chipset integrated into this adapter is the heart of what makes it work properly. I have tried numerous other USB adapters with different chipsets and the PL2303HX produced the most consistent and accurate serial data transfers. I ran tests using a legacy laptop running Windows XP and a standard DB9 serial port against a new Windows 7 x64 Laptop with the Plugable USB adapter and performed data captures and transfers with a Cisco router. I did encounter a few problems when performing large file transfers, but the same problems were also encountered using the legacy serial port. Unlike other USB adapters, I experienced no bit inversions, no lost connection, no console port lockups, and no baud-rate changes.

    The Drivers provided by Plugable are also great. Drivers are available for Windows XP x32, Windows 7 x32, and Windows 7 x64, as well as MAC OSX. I did not have a Mac available for testing, but the drivers and adapter worked perfectly under the 3 windows environments tested. You will most likely need to change your COM Port assignment each time you reboot Windows or change to a different USB port, as windows will Dynamically assign a COM Port on a first-available basis. However, I have noticed that once I disabled the non-existent serial port in the BIOS of my machine, my COM assignment stayed the same as long as I used the same USB port. If all of this is a bit too technical for you, the provided PDF user manual offers step by step instructions with accurate screen shots for Windows Vista/7 and 2000/XP. Mac instructions are also included, but I have not verified them.

    These adapters are great. Although they didn't work on my particular application, the plugable support team was very responsive and helpful...way more than any other company I've ever dealt with. And when we couldn't resolve the problem with a old device not talking to the new chipset, they refunded my purchase.

    Reviewed in Canada on August 25, 2022
    I bought this to go from my Microsquirt to my laptop. It was a bit of a pain, I'm not tech savvy but I downloaded the drivers off their site despite them saying windows 10 did not need this, then had to update windows and finally reboot the laptop and it saw my device. Really not very difficult and it has worked perfectly.
