The short version is that USB-A doesn't beat USB-C on capability. "USB-A" and "USB-C" describe the shape of the plug, not the speed, power or features behind it. A Type-A port can be USB 2.0 or 10Gbps, and a Type-C port can be anything from basic to 40Gbps USB4. What USB-A still has is a huge installed base and a simple, predictable power model.
1. It can charge some USB-C gadgets that refuse C-to-C
This is the most surprising item on the list, and the best supported. Some devices have a USB-C port but won't charge from a USB-C charger. They charge fine from a USB-A-to-C cable.
The cause is the way USB-C decides which end supplies power. Plugable explains that the plug's shape no longer determines the direction of power flow, so devices use the configuration channel (CC) pins to negotiate it. A compliant device announces that it wants power with 5.1 kΩ pull-down resistors on its CC pins. Without them, the charger sees nothing to power.
Plugable says the likely culprit is a device that lacks the required pull-down resistors, and that USB-A will always provide 5V. Hackaday's "manufacturer sins" piece is blunter. It says the cause is a designer who saved one cent and skipped testing.
This is a workaround for badly designed devices, not an inherent USB-A strength. It also doesn't mean USB-A can deliver more power. USB-C's negotiated power is far richer. Cable Chick's comparison describes the A-to-C route as simple 5V charging, while C-to-C supports negotiated charging. Anything this fussy is usually a small accessory, such as earbuds, trackers, lights or Qi pads.
What to do if a gadget won't charge over C-to-C:
- Try a USB-A-to-C cable. Many of these devices ship with one in the box.
- Use the cable the manufacturer includes.
- Don't assume the charger or your USB-C cable is faulty.
2. Your existing peripherals still plug straight in
Mice, keyboards, printers and webcams with Type-A plugs keep working on any machine with a Type-A port. On a USB-C-only laptop you need a dongle or hub, which means another accessory and another thing to lose. That is a real convenience gap, but it is installed-base convenience, not technical superiority. The original piece's claim that USB-A is "the most widely accepted connector" is plausible, but I found no measured market data for it.
3. Wireless receivers are still often USB-A
Plenty of wireless mice and keyboards ship with a small Type-A receiver. Logitech's own guidance on its Unifying receiver says to plug it into an available USB-A port. The Unifying receiver can pair up to six compatible Logitech devices. Logitech also points to its newer Logi Bolt receiver as the choice for business environments.
Not every wireless peripheral uses Type-A, since Bluetooth and other receiver formats exist. A Type-C receiver wouldn't make a mouse faster, because the radio link sets responsiveness, not the plug. That is a general engineering point, not a tested result.
4. BIOS FlashBack needs a specific port
This is the most useful item for anyone building or repairing a PC. On supported ASUS boards, BIOS FlashBack updates firmware without booting Windows or entering firmware setup. ASUS says it's meant for when a board can't be turned on, or the power light is on but nothing is displayed.
ASUS's published procedure goes like this:
- Use a USB flash drive of 1GB or more. ASUS requires a single-sector drive in FAT16/32 MBR format.
- Download the BIOS file for your exact board model from the ASUS Download Center.
- Extract it, run the BIOSRenamer tool to rename the .CAP file, and copy that file to the drive's root directory.
- Plug the drive into the board's marked FlashBack port.
- Shut the system down but leave the power connected. Hold the FlashBack button for three seconds until the LED blinks three times.
- Wait for the light to go out. ASUS warns not to remove the drive, cut power or press Clear CMOS during the update, and says the update can take about 8 minutes.
If the LED flashes for five seconds and then goes solid, the process failed. ASUS suggests checking the drive's format, the BIOS file and its name for your board. You can confirm success by entering BIOS setup after booting and checking the version.
A caveat on ASUS's 800-series boards: ASUS says the Management Engine firmware must be updated separately after a FlashBack update. FlashBack isn't universal either. The port, file naming and button procedure vary by vendor and model, so follow your board's manual. This ASUS guide is for ASUS boards only.
5. Desktops still have plenty of Type-A ports
The original piece cites ASUS's ProArt X870E-Creator WiFi, and the number checks out. ASUS's spec page lists 11 rear USB ports: two USB4 (40Gbps) Type-C, one USB 20Gbps Type-C, seven USB 10Gbps Type-A and one USB 2.0 Type-A. That's eight Type-A and three Type-C ports.
One correction to the article's framing. It says most desktops have zero rear USB-C ports, and that a board with any probably has no more than a couple. This board has three at the back, and they are the fastest ports on it. A premium board having more Type-A than Type-C ports is a fair observation. "Chances are your PC has no rear USB-C" is anecdote, not data.
6. One flash drive works across devices
Type-A flash drives plug into consoles, TVs, routers and PCs. Some of this depends on the specific device:
- PS5: Sony's FAQ says you can play PS4 games from a USB drive. The drive should be USB 3.0 or later, between 250GB and 8TB, and formatted as extended storage. It can't go through a hub. PS5 games have to run from internal storage. Sony's FAQ doesn't describe a screenshot-transfer workflow, so check the console's current media options.
- Routers: TP-Link documents plugging a drive into a supported router and reaching it over the network. Windows users can use SMB or FTP, and TP-Link recommends enabling the Secure Sharing option. Remote access is FTP-only. Support varies by model.
The verdict
USB-A's real advantages are narrow, practical and mostly about legacy. They are dependable 5V power on a basic port, a huge installed base, receivers and drives that plug in without adapters, and firmware-recovery ports that expect Type-A. USB-C is better for speed, power delivery and reversibility. At 30, USB-A has less to prove than USB-C does, and it still has plenty of ports left on your desktop.
